The Burton Performance Midweight Sock wraps your foot in a breathable blend of woolly warmth and rider specific support and cushioning for a successful day on the slopes. A polypropylene reinforced footbed and merino wool fibers deliver quick-drying and odor-resistant properties for lasting freshness while all over elastic support and strategically placed Sock Lock reinforcements add extra support and comfort when you're lapping your favorite runs. And with medium-density cushioning at your instep, shin, and calf, you'll be riding in comfort through the entire day even when your laces and straps are cranked tight.
