How to choose running shoes: 6 questions to find the right pair

You have bought the wrong running shoe at least once. It looked great on the shelf, a friend recommended it, the online reviews were glowing, and then it felt uncomfortable from the third kilometre on. It happens to everyone, because working out how to choose running shoes is harder today than it was ten years ago: more categories, more foams, more technologies, and every brand tells its story as if it were the only one.

In our stores we have worked the same way for years: before showing you a shoe, we ask you a few questions. Where you run, how much, with what goal, what you like to feel underfoot. In this guide you will find the same questions, in the same order, with explanations to help you answer. At the end you will find the Shoe Finder, the guided path that puts them together for you and suggests the shoe that fits you best.

Why choosing running shoes today is so hard

A few years ago the choice was simple: neutral or stability, cushioned or lightweight. Today the same category includes models with 30 and with 45 millimetres of foam under the heel, rocker geometries that roll you forward, carbon or nylon plates even in training shoes. Spec sheets all look alike and model names do not help.

The result is that many runners choose using criteria that have little to do with running:

• the colour, or the best-looking shoe on the wall;
• the review of the moment, written by someone who weighs, runs and lands differently from you;
• a friend’s shoe, which works perfectly for them;
• the “most cushioned” model, as if more foam always meant more protection.

Getting it wrong costs money, uncomfortable kilometres and sometimes niggles that stay with you for weeks. The good news is that you do not need to become a foam expert to choose well. You need the right questions, asked in the right order.

1. Where do you run? Road, gravel or trail running shoes

This is the first question because it decides the family of shoes before the model. Outsole, protection and stability change completely between asphalt and trail.

Road

Most runners run here: streets, cycle paths, pavements, paved parks. Road shoes have smooth or shallow-grooved outsoles, rubber compounds designed to withstand the abrasion of asphalt and light, breathable uppers. It is the widest category, where you find every kind of feel: from the softest shoe for slow long runs to the race shoe.

Mixed surfaces and light gravel

Riverbanks, gravel roads, packed dirt, wide paths with no technical sections. A road shoe usually works, especially if it has a slightly grippier outsole. If gravel is your main surface, there are hybrid (road to trail) models with low lugs: they hold on loose ground without feeling awkward when you get back on the road.

Trail and technical trail

Here everything changes. On trails you need deeper lugs, a rubber that grips wet rock, toe protection and an upper that keeps your foot locked in on descents. The more technical the terrain (scree, roots, steep gradients), the more grip, stability and protection matter, and the less weight matters. For an example of how to evaluate a trail shoe, see our guide to the La Sportiva Prodigio 2, a trail shoe for training and long distances.

Track

For track intervals, runners use light and responsive shoes, often the same ones they use for fast sessions on the road. Spikes are a world of their own, designed for athletics.

Do you need a waterproof shoe?

Versions with a Gore-Tex (or equivalent) membrane keep out water, mud and snow. In exchange they are warmer and less breathable than a mesh upper, and if water gets in over the ankle (a deep puddle, a stream crossing) it stays inside. They make sense if you often run in winter, in the rain, on wet ground or on snow. If you run mostly in summer or in good weather, a regular shoe that dries quickly is the better choice.

2. What role will it play in your rotation? How many running shoes do you need

This is the question almost nobody asks, and it is the one that changes the choice the most. A shoe does not have to be “the best”: it has to be the best for the job you will give it.

• Only shoe. If you run two or three times a week and want a single pair, you need a versatile shoe: protective enough for long runs, lively enough for a few strides. No extremes.
• Main training shoe. The one that racks up the most kilometres. It must be comfortable and durable, because you will use it for most of your runs.
• Second, faster shoe. Lighter and more responsive, for intervals, progression runs and tempo. It does not have to do everything: it has to shine when you push.
• Race shoe. Designed for race day and a few specific sessions. It often has a plate and very responsive foams, and it lasts less.
• Protective or recovery shoe. Soft and generous, for easy runs after a hard session or a race.

Owning more than one pair is not a luxury. A study published in 2015 in the Scandinavian Journal of Medicine & Science in Sports followed more than 260 recreational runners: those who alternated several pairs of shoes had a 39% lower injury risk than those who always ran in the same pair. Rotating your shoes also makes them last longer: we have written a dedicated guide on how to make your running shoes last longer.

If you do not run much, though, start with one well-chosen versatile shoe. The second pair comes when you start doing different sessions during the week.

The only shoe does everything well, the second shoe does one thing brilliantly.

3. What runs will you do most often? From walking to race pace

The role tells you where the shoe sits in your week. The type of run tells you how it will be used.

• Walking and everyday use. Many people use running shoes for walking, and they are right: cushioning and comfort are designed for hours of use. We explain why in 5 reasons to use running shoes for walking. Here comfort and stability matter, not responsiveness.
• Easy running. Relaxed pace, runs of 30-60 minutes. You need a comfortable shoe that does not tire you.
• Long runs. Beyond 90 minutes, protection and upper comfort over distance become key. A shoe that is fine for 8 km can become annoying by the twentieth.
• Tempo and faster paces. Progression runs, tempo, intervals: here you need a shoe that returns energy and is not heavy.
• Racing. Lightness and responsiveness first, even at the cost of some durability.
• A bit of everything. It is the most common answer and an honest one. In this case the right choice is almost always a balanced shoe that does not excel at anything but never lets you down.

4. What feel are you looking for? Cushioned, stable or responsive running shoes

This is the most personal part. Two runners with the same weight and pace can prefer opposite shoes, and both are right. Underfoot feel is the criterion spec sheets describe worst, and the one that matters most for comfort.

Feel	Underfoot	Typical features	Ideal for
Soft and comfortable	Your foot sinks in, you barely feel the impact	High stack, soft foam, wide base	Slow long runs, recovery, runners looking for protection
Balanced	Neither too soft nor too firm	Medium stack, versatile foam	Only shoe, daily training
Stable / protective	Your foot is guided, the shoe does not “give” sideways	Wide base, sidewalls, guidance elements	Runners whose foot or ankle feels unstable, long runs when tired
Responsive / fun	The shoe bounces and invites you to speed up	Springy foams, low weight	Tempo, progression runs, runners who love a lively ride
Aggressive / fast	Stiff, propels you forward	Plate (carbon or nylon), rocker geometry, minimal weight	Races and specific sessions

Two things to keep in mind. First: soft does not mean more protective for everyone. On a very soft shoe some runners feel unstable and work harder. Second: a responsive shoe is not only for fast runners. If you like to feel the ground and a “lively” shoe, it can be the right choice at easy paces too.

If you already know you want maximum softness, you will find a selection in our article on the best cushioned running shoes.

5. Do you have a favourite brand, or one to avoid?

It may look like a matter of taste, but it is very practical. Every brand builds its shoes on different lasts: some fit narrow, others have a roomier toe box, others a more wrapping heel. Some brands make wide versions (wide, 2E or 4E) of several models, though not always in every colourway.

If a brand has always fitted you well, it is a great starting point. If another has always bothered you at the toes or on the instep, it makes sense to rule it out: the problem is probably not the individual model, but the last. Keep in mind, though, that differences can be big even within the same brand, as we explain in our guide to choosing the right On Running model.

6. What shoe do you use now? The most underrated starting point

When a runner walks into our store, the most useful question we can ask is: what shoe are you using now, and what do you like or dislike about it? It is valuable information, because it tells us where we are starting from.

“I like it, but after 15 km it feels flat” means you need more protection. “It is comfortable but heavy” opens the door to something more responsive. “It hurts under the arch” calls for attention to the shape of the shoe and to stability. The drop you use today also matters, because changing it a lot requires an adaptation period.

That is why the Shoe Finder asks you, optionally, which shoe you use now and what you think of it.

Neutral or stability? Pronation, drop and weight: what really matters

If you have already searched for how to choose running shoes, you will have read mostly about pronation, drop and runner weight. The Shoe Finder does not ask you directly about any of these three. Here is why, and how we take them into account anyway.

Neutral or stability shoes: how to know if you need them

Pronation is the natural movement by which the foot rolls inwards as it lands: it helps absorb impact. For years runners were told that those who pronate “too much” must use a stability shoe. Research has scaled back this idea: a study published in the British Journal of Sports Medicine on novice runners wearing neutral shoes found no higher injury risk in those who pronated compared with those with a neutral foot strike.

Today the most widely used criterion is comfort, what biomechanist Benno Nigg called the “comfort filter”: the shoe that feels most comfortable and stable to you is often also the one best suited to the way you run. Stability shoes have not disappeared: they have become softer and “guide” the foot instead of blocking it. If you feel secure in a shoe that holds you, they are the right choice. That is why in the Shoe Finder stability is a feel you choose (“stable / protective”), not a label assigned to you. You will find the models in our stability shoes category.

If you have recurring pain or injuries, choosing a shoe is no substitute for an assessment by a healthcare professional.

Running shoe drop

Drop is the difference in height between heel and forefoot. It does not measure how much cushioning there is, but how the foot is tilted inside the shoe.

Drop	Range	What changes
0-4 mm	Low	Flatter footstrike, more work for calf and Achilles tendon
5-8 mm	Medium	Versatile compromise, suits many runners
9-12 mm and above	High	Less load on calf and tendon, favours heel striking

The most useful rule: stay close to the drop you are used to. Dropping a lot, for example from 10 to 4 mm, is possible, but gradually. On every product page of our site you will find drop, weight and category: we explain them in our guide to technical specifications.

Runner weight and shoe weight

If you are heavier, you will generally be better off with more structured shoes with more foam, which handle the load over distance without compressing too early. If you are light, you can afford lighter, more minimal shoes even for training. Our product pages include the recommended athlete weight for each model. Shoe weight, on the other hand, matters mostly for fast paces and racing: for easy running, a few extra grams in exchange for comfort is almost always a good deal.

Size and fit: the part no quiz can do for you

You can choose the perfect model and get it all wrong with the size. A few simple rules:

• Leave about a finger’s width at the toe (roughly one centimetre) between your big toe and the end of the shoe. When you run, your foot moves forward and lengthens.
• Try shoes on in the afternoon or after walking: your feet swell during the day, and the same happens when you run.
• Wear the socks you run in. A thick or thin sock changes the fit more than you think.
• Your heel must stay put. If it slips, try lacing through the last eyelet (the so-called “runner’s knot”) before changing size.
• Half a size up is normal. Many runners wear half a size or a full size larger in running shoes than in everyday shoes. What counts is the length of your foot, not the number on the box.
• Check the width too, not just the length: if you feel pressure at the sides, look for a roomier model or a wide version.

The best way to be sure is to try them. You can do it in our stores or at home: order online, try them indoors on a clean floor and, if the fit is not right, use the return service.

How the MioMio Run Shoe Finder works

The Shoe Finder is the guided path we built to bring together all the questions in this guide. It is free at miomiorun.com/en/shoe-finder and takes less than a minute.

The questions, in order:

1. Who the shoe is for (men or women)
2. Where you will use it: road, mixed, light gravel, trail, technical trail or track
3. Whether you need a waterproof (Gore-Tex) version
4. What role it will play in your rotation
5. What runs you will do most often
6. What feel you are looking for
7. Whether you have a favourite brand, or one to avoid
8. Which shoe you use now and what you think of it (optional)

What is behind it. Every shoe in our catalogue is rated by our team on four parameters: comfort, cushioning, stability and responsiveness. These are not marketing figures, but the judgement of people who try, sell and talk about shoes with runners every day. The Finder matches your answers against these ratings.

What you get. The shoe that suits you best, with the reason for the choice and its scores, plus two similar alternatives if you want to compare. From there you can open the product page, check sizes and availability and order it.

The most common mistakes when choosing running shoes

1. Choosing on looks. The right colour does not make up for the wrong fit.
2. Copying someone else’s shoe. Weight, pace, footstrike and foot shape are different.
3. Buying a race shoe for everyday training. It lasts less, is less stable and is not designed for that.
4. Buying your casual shoe size. Running shoes almost always need more room.
5. Changing drop or category all at once. Every big change should be introduced gradually.
6. Keeping the same shoe for too long. When the foam is compressed, protection drops even if the upper looks new.
7. Thinking more cushioning is always better. More foam is a feel, not a guarantee.

Frequently asked questions about choosing running shoes

How do I know which running shoe to buy?

Start from where you run (road, gravel or trail), then from what role the shoe will play (only shoe, training, racing or recovery), what runs you will do in it and what feel you want underfoot. Brand, drop and size come afterwards. If you want a quick answer, the MioMio Run Shoe Finder matches these answers against our team’s ratings and suggests the shoe that suits you best.

Which running shoes should a beginner choose?

A balanced or soft only shoe, comfortable and protective, with a medium or high drop. Avoid plated race models: they are designed for something else. The most important thing is that it feels comfortable from the very first step. You will find some models in our article on the best running shoes to start running.

How many running shoes do I need?

If you run two or three times a week, one versatile shoe is enough. When you increase your mileage or start doing faster sessions, a second, more responsive shoe makes sense. Alternating several pairs also helps vary the stimulus and makes each pair last longer.

Should I go half a size up?

Often, yes. In running shoes you need about a finger’s width between your big toe and the tip, because your foot lengthens and swells when you run. Many runners wear half a size or a full size larger than in everyday shoes. What counts is the actual length of your foot, not the number.

How long do running shoes last?

Roughly between 500 and 800 kilometres, but it depends on runner weight, surface, model and foam. The lightest race shoes last less. The most reliable signal is feel: if the shoe seems flat or hard compared with when it was new, the foam has lost part of its properties.

Are running shoes good for walking?

Yes. Cushioning, comfort and lightness make them excellent for walking and everyday use too. For this use, soft or stable models with a wide outsole are the best choice.

Is the Shoe Finder free? How does it choose the shoe?

Yes, it is free and available in Italian, English, French, Spanish and German. It asks a few questions about terrain, use, type of run, feel and brand, then matches your answers against our team’s ratings for comfort, cushioning, stability and responsiveness. It suggests the shoe that suits you best and two similar alternatives.

The right shoe is the one that runs like you

There is no single best running shoe. There is the right one for where you run, for the job you will give it and for the feel that makes you comfortable. If you ask yourself the six questions in this guide, you have already done the hardest part.

The Shoe Finder does the rest: one minute of questions and you have your shoe, with the reasons and two alternatives. Then try it on, in one of our stores or at home.
