The Cosmic Ultimate Tri is our premium shoe for pro-level triathletes, and is the choice of athletes like Frédérik Van Lierde and Mike Aigroz. Like all our triathlon shoes, it excels in two key areas: power transfer and transition practicality. The design is based on our lightest road shoe with a full carbon SLR outsole and heel lock, maximizing your ability to push and lift the pedals without your feet moving in the shoe at all. And for smooth transitions, a large Velcro strap and oversized heel loop make securing the shoe fast and easy as you jump on the bike – or even once you’re riding. And its lightweight mesh upper and soft interior means wet, sockless feet are quickly wicked dry so you stay comfortable on your ride.
