Built in collaboration with Danner, the Patagonia Foot Tractor Felt Wading Boot is designed for the most demanding anglers. The Foot Tractor is constructed with the durability for spending many hours of many days on the water, thanks to its treated, full-grain leather upper and nylon panels that withstand freshwater, saltwater, and the abrasive nature of obstacles in either. Underfoot, polyester felt provides grip in slippery conditions-excelling especially on slippery or mossy rocks-while a rubber midsole provides stability and rebound to reduce fatigue throughout the day. Perforated drains sit on each side of both boots, enabling the Foot Tractor to shed absorbed water quickly to reduce the strain on your legs by limiting weight.
