Product Description


The X03® brings even more cushioning to the signature control and confidence of TerraSkin®. Made with a more accessible fit to suit more runners. Athletes from beginners to elites tell us the comfort makes them want to go further. It's the perfect partner for any for any off-road training runs and your first ultra races.

UP TO 27% MORE TRAIL CONTACT

UP TO 27% MORE TRAIL CONTACT

Inspired by spider webs, the lugs on the SpinWeave® outsole flex depending on the terrain. Independent research shows this increases ground contact by up to 27% vs. competitors, maximizing the unrivaled traction of Vibram® MegaGrip rubber.

SKIN-TO-TRAIL CONNECTION

SKIN-TO-TRAIL CONNECTION

TerraSkin® is a shoe-and-sock system built on 30 years of X-Bionic next-to-skin expertise. The sock works with the shoe to boost airflow through aligned ventilation, while targeted GripYarns connect with the sockliner to improve hold.

VERTICAL CUSHIONING, LATERAL STABILITY

VERTICAL CUSHIONING, LATERAL STABILITY

The patented SpeedFrame® construction lets the soft foam core cushion vertically on landing while stabilizing the foot horizontally. It's like mountain bike suspension for your feet, giving you cushioning and precise control on uneven ground.
