Sock Geek Says:

"The Original" Double Layer Anti-Blister System run sock demanded by Wrightsock fans.  Flat knit (no cushion) mid-weight sock designed for all running activities.  Less bulk doesn't compromise shoe fit.  Features a great combination of moisture management and friction-free control.
