DeFeet quality at an "entry level" price. Budget conscious athletes need quality construction as much as anyone. Sometimes more. Thus, the Acti•V•Ator™ concept was born. In DeFeet`s outline for the Acti•V•Ator™, several benchmarks were laid out. Just because it`s their least expensive doesn`t mean it can be a slacker. Most brands distance themselves from their products by leaving the USA for cheaper construction. DeFeet is proud to make the Acti•V•Ator™ themselves and offer it at this price. • Stayfast™ cuff provides a secure, durable, dynamic fit. • Sculpted Air•E•Ator® mesh weave travels all the way around the sock to aid airflow and moisture transfer. • En•Duro•Skin™ construction reinforces the external heel and toe "puncture" areas
