This is the SALOMON SPEEDCROSS 6 GORE-TEX. I wore these a few times for mountain climbing, but there are no noticeable stains. The SPEEDCROSS 6 is a trail classic, true to Salomon's roots. This version has been further enhanced while pursuing weight reduction, with excellent grip that firmly grips the ground and smooth mud shedding. The waterproof and breathable GORE-TEX membrane is perfect for wet ground and mud. The upper is also a new design, but the traditional comfort of the SPEEDCROSS remains. The waterproof and breathable GORE-TEX membrane keeps your feet dry, and comfort continues even in harsh conditions such as mud.
