The Micro Light Performance Trail looks different for a reason. The high cuff is a built-in scree-guard that helps keep out the trail while you're trail running. Below the cuff is a vented lower that increases breathability during highly aerobic activities.

• Our patented Full Contact Fit^® hugs the contours of your foot and stays put so there are no loose socks to rub you the wrong way.
• Hybrid performance cuff sits between a quarter and a crew height for added protection.
• Extra cushioning in the heel, toe and the arch.
• Quarter height is just above your boot line.
• Increased durability in high-abrasion areas.
