Some training runs are meant to push you past your comfort zone, but that doesn't mean your feet. With our Women's Run Targeted Cushion Low Ankle sock, you get features meant to help your feet stay comfy, like a women's specific fit, breathable mesh zones, and an Achilles tab to reduce slippage. Plus, the targeted cushioning on the ball and heel of the foot gives those high-strike areas some extra padding. And it's all punctuated with Merino wool construction, which offers soft, breathable odor resistance and temperature regulation. These socks will help ensure that, even if the cardio is uncomfortable, your feet won't be.
