Product Description

The ultimate triathlon race shoe

The Cosmic Ultimate Tri is our pro shoe for triathletes, worn by the likes of Frédérik Van Lierde and Mike Aigroz. Like all our triathlon shoes it’s super strong in two areas: power delivery for the cycle and practicality for the transition.

Power-wise, it’s based on our lightest road shoe with a full carbon SLR outsole and heel lock giving huge power transfer and the ability to push and lift the pedals without your feet moving in the shoe at all.

And for transition, a large Velcro strap and oversized heel loop make securing the shoe easy as you jump on the bike – or even once you’re riding. What’s more, its lightweight mesh upper and soft interior means wet, sockless feet are quickly wicked dry and kept comfortable throughout the cycle.

Weight : 240 grams (8.5)

Sizes: From 5 to 12
