Ultra marathons demand performance that handles hours of running on varied terrain. Our Ultra Run series features our midweight cushioned terry underfoot and around each toe. It’s a unique approach that creates truly comprehensive cushioning – toe sleeves included – to soften the repeated impact encountered during ultras. Our patented five-toe design eliminates skin-on-skin friction between your toes, promotes a natural splay on impact, and frees you to utilize your entire foot on shifting terrain. Our Ultra Run socks are available in crew and no-show heights and feature gender-specific designs.
