Sock Geek Says:

Attention:  The White/Sweatshirt Grey color in this sock has been discontinued by Wigwam.  Get 'em while they last!

An impact softening, lightweight, semi-cushion sole keeps feet healthy and active even during the most intense runs. Breathable mesh instep and seamless toe enclosure. Patented moisture control system reduces the chance of blisters. Foot hugging fit with a slight heel tab that prevents sock from slipping. Great durability for frequent use.
