Streamlined and light, this is a versatile sock for all kinds of runners. It keeps your feet dry and cool - mesh at the top and COOLMAXA(R) EcoMade fibers move moisture and let things breathe - and our unique toesock design protects each toe from blisters, hotspots, and moisture buildup. The ergonomic fit and integrated arch support hug your feet, your toes are free to splay for better alignment, and the mini-crew sits just above the ankle to provide protection and freedom.
