A midweight over-the-calf sock, built for a full day in your boots.
Medium-density cushioning for comfort, a breathable polyester blend that keeps your feet warm, and elastic ankle and calf support so it stays put. Mesh-knit zones on the shin and over the top of the foot let heat out when you're working hard.

Midweight
Midweight padding keeps a stiff boot comfortable through a full day, without the bulk of a heavyweight sock.
94% polyester
Polyester takes on almost no water, so sweat moves off your skin instead of soaking in. Mesh-knit zones on the shin and over the top of the foot let heat and moisture out, while the insulating blend keeps your feet warm.
Ankle + calf
Elastane knit through the ankle and calf gives a secure fit, so the sock stays put inside your boot instead of slipping down.
Over-the-calf height, so it rides above the top of your boot.
Medium-density cushioning for comfort inside the boot.
Mesh-knit panels on the shin and over the top of the foot.
Elastic ankle and calf support for a secure fit.
A knit heel cup keeps the sock sitting right at the back of your foot.
A ribbed cuff with our E mark knit in.

Every zone is knit straight into the sock: mesh where your shin and the top of your foot need to breathe, a cushioned midweight body, a shaped heel, and elastic support at the ankle and calf. ENDEAVOR runs along the sole, and our E mark sits on the cuff.
