Technical specifications guide

The Cielo X1 3.0 is pure racing speed, designed for those who live in the fast lane and aim for peak performance. It is the flagship competition shoe and the lightest ever made in its category, with a weight further reduced compared to the previous version for an even more explosive and responsive feel.

Designed to boost your stride, it features a carbon fibre propulsion plate that works in synergy with the ultra-soft and responsive PEBA foam, offering high energy return and instant acceleration. The refined heel shape improves stability and control at high speeds, whilst the asymmetrical lacing system ensures a more secure and snug fit.

The cutting-edge open-weave fabric upper guarantees extreme breathability and lightness, supported by a dynamic stretch tongue (patent pending) that follows the foot’s natural movement. The moulded compression polyurethane sole offers superior traction, essential when chasing track records. Minimalist materials in the heel and tongue complete a shoe built to go fast, without compromise.
