This is the cutting edge Enduro sock. It's foundation begins with Earth-friendly COOLMAX EcoMade fibers that move moisture to keep feet dry and comfortable on all day trail rides. The high density forefoot pad comes in handy when maneuvering down the steepest, most heinous gradients on the mountain. The 6" tall ribbed cuff doesn't look like you just climbed off your tri bike - and it protects your bones from all those sharp, prickly things you rip through. Wear them and enjoy the flow more than ever.
