Your Winter Boots are made of a foam material on the sole. How is durable is this foam sole?

Stonz Winter Boots are certified as having 2x the industry standard for skid resistance and 19x the industry standard for sole abrasion. Some of our customers walk up their steep, icy driveways with no slipping in sight! Others have reported back that their Boots are still in great condition after a whole winter of serious trekking on sidewalks and snow.
