Fast summer hiking never looked as great as the sleek, lightweight X Ultra Mid Aero Women's. Light enough to move as fast as you want, breathable, and with a supportive mid-height cut, this boot looks as fast as it feels. When your feet get too hot, it makes for a bummer of a day.

Aggressive lugs with a reverse chevron pattern help the non-marking Contagrip sole claw into any surface, for confidence on every hike. These boots also feature: Injected EVA and molded shank midsole, EVA shaped footbed and OrthoLite sockliner, textile lining material, and protective rubber toe cap. Material: Manmade, Textile.
