Designed to power through uphills and descents, the X ULTRA is now available in an all-winter version. Just as agile as a trail-running shoe, it offers all the stability, grip and protective comfort you need to tackle wintery terrain and cold temperatures. Not to mention cozy 3M Thinsulate™ insulation.
We’ve added a grippy Winter Contagrip® outsole that thrives in the ice and cold, as well as a gaiter hook if you need more protection.
Keep warm and dry with 3M Thinsulate™ 200g insulation, a CS waterproof membrane and cozy liner.
The ADV-C Chassis targets articulations on the outer foot to optimize stability without limiting your mobility.
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.
