The Injinji five-toe original – this is the sock that started it all. The Sport Original Weight Crew’s COOLMAX® fibers wick moisture off the foot for comfort on long runs, intense workouts, and outdoor adventures. The patented design protects your toes from the skin-on-skin friction that causes blisters, and allows your toes to splay and work independently for better feel and confidence on tricky terrain. The mini-crew height keeps dirt and debris out, arch support is built in, and the form-fitting five-toe design works with all your shoes – including your après activity flip-flops.
