Size 6 fits paws 2.6-2.8 in wide and suits medium Samoyeds, Siberian Huskies, Labradors, and similar breeds. The toe cap is made from tough, waterproof space leather, while the upper is a tight-weave air-mesh. Soft, lightweight, anti-slip rubber soles give reliable traction on hardwood, tile, wet sidewalks, or trails. Wide split openings slip on like socks, and two adjustable Velcro straps lock the booties in place.
