Nike Burrow Men's Slipper KEEP IT COZY. There's nothing like cozying up to a campfire. Nothing like adventure. But also, there's nothing like the comfort of home. The Nike Burrow lets you bridge worlds. Slip them on and get lounging or step out of the tent and enjoy the fresh mountain air. Its fleece-like lining helps keep you warm. The marshmallow soft foam midsole/outsole with grippy traction pattern adds spring to your step. Foam midsole/outsole adds lasting comfort. Fleece-like material lines the inside (and sockliner) for added warmth and comfort. Zipper pocket on the top lets you stash small items like keys or cash and makes a playful nod to Nike Tech Fleece. Outsole traction pattern helps on a variety of surfaces.
