The Outdoorsman NuCraft is designed to renew any rubber-soled hiking, hunting, or work boots including Timberland, Red Wing, Wolverine, and all other popular boot brands. For the Authorized Ecco Renewal Program and Warranty, please see our Ecco page. Please see our Western NuCraft for the renewal of all western footwear. With the Outdoorsman NuCraft we replace the original sole with the nearest equivalent Vibram™ rubber sole. When choosing the sole, characteristics such as sole and heel thickness and styling, density, weight, and durability are all considered.
