Specifically designed heel to toe to fit a womens foot, Injinji’s lowest-bulk sock is built for all types of runs. A narrower profile, increased stretch, and redesigned toes create a better fit with improved compression and support. Their unique five-toe design eliminates the friction that can cause blisters and keeps your toes free for a natural splay and better feel on uneven terrain. A mesh top and COOLMAX EcoMade fibers help keep feet dry and cool, and the no-show cuff rests below the ankle and features a heel tab to minimize slipping and chafing.
