Gravity? What gravity?
At just 124g, the TerraSkin® X-SLR is the barely there vertical kilometer racing shoe is engineered to hit the summit at lightspeed.
The ultralight monofilament upper and a radical heel design strip away weight. SpinWeave® grip and a carbon insert keep forefoot control and propulsion on steep inclines.
Less shoe. More speed and control uphill. ⚡️

Feeling supernatural at the finish of OCC.
X-Bionic athletes Alain Santamaria Blanco and Anton Gustafsson took 5th and 6th in the men’s race, crossing the line less than a couple of seconds apart.
And Naiara Irigoyen took 11th in the women’s race.
All racing OCC by UTMB for the first time. And all giving every bit of sweat and fight in relentless heat to bring it home.
We couldn’t be prouder of them.
