Features of the Ultralight Mid Sock

Technology

The Ultralight Mid Sock is a performance running sock with ankle coverage to keep the dirt and dust at bay. Lightweight and protective, thick heel and toe padding combines with anti-blister patches. Because on race day, little details can make a big difference. Get off on the right foot.

Materials

As you pile on the miles, cool and dry feet are what it's all about. That's why On created an underfoot mesh to remove heat from where it's needed least. So the only thing that's heating up are your lap times.

Design

When we want to go fast, we all want a sock that is barely there. A sock that hugs your feet, a sock that feels like a second skin. With a snug and supportive toe box and an ultrafine gauge yarn, this sock is all about that feeling of running sockless yet supported. This sock is all about performance.
