I find these are great for man-made trails in the dry or damp, not so much if it's proper wet. If you're getting onto clayey mud and wet roots I would go for something different as skiing sideways on them last weekend wasn't so confidence inspiring. I've been recommended the Schwalbe Hans Dampfs and Specialized Storms but haven't tried either yet.
