For the roughest and toughest of mountain bike trails, the 8" Defend Crew Socks add extra comfort for your feet. This comes first and foremost via the trail-specific zones that add extra cushioning in more vulnerable areas of the foot. A cushioned shin area is particularly welcome if you ride flat pedals. Comfort also comes via the compressive arch support, giving a smooth and comfortable fit inside your MTB shoes. A rib-knit upper locks your socks in place so there's no annoying slippage and flat-stitch toe seams prevent irritation too. When MTB-ready comfort and protection are your priorities, you can't beat the 8" Defend Crew Socks.
