Trail running is fun, but stopping every 30 feet to take trail debris out of your no show socks is more annoying than being passed by the geezer and her walking staff ... um, yeah that's a cane. The Feetures! Merino Lightweight Crew Sock rises above your ankles to keep rocks and dirt out of your socks. The Perfect Toe takes away irritating toe seams and works with the anatomical fit to reduce blisters and chafing. High density cushioning in high impact areas softens your footfall for a cushier ride.
