Get ready to power through uphills and descents with the updated X ULTRA 4. It is as agile as a trail-running shoe but with all the stability and grip you need to tackle technical terrain. Equipped with a new chassis, the shoe is even better at protecting sensitive articulations without compromising freedom of movement.
Drawing on our trail-running expertise, this shoe is lighter and more agile, so you stay nimble on uneven terrain.
The new ADV-C Chassis targets articulations on the outer foot to optimize stability without limiting your mobility.
The Contagrip® MA outsole grabs the terrain, even when it’s wet or slippery, giving you more control especially on descents.
1. Place a sheet of paper on the floor and against a wall.
2. Make sure you are wearing the same socks that you would normally wear with this type of shoe.
3. Wearing these socks, stand on the sheet of paper with your foot perpendicular to the wall and your heel against the wall.
4. Then use a pen to draw a line just in front of your big toe. Repeat for both feet and take the longer distance to determine your size.
5. Using a ruler, measure the distance between the wall and the line you drew to find your size.
