We source the leather for our work boots from Wild Idea Buffalo Company in South Dakota because of their recognition of the American bison’s role in regenerating the prairie ecosystem of the Great Plains. Long treasured over cowhide for its stronger, more durable and elastic material, bison leather makes an exceptional work boot. The Men's Wild Idea Work Boots is fully backed by our Ironclad Guarantee and you can find it on Patagonia.com. | Patagonia Men's Wild Idea Work Boots in Owl Brown, Size 7
