After you've logged many hours headed to the river or bay to fill the cooler with freshly caught fish, the aluminum bar sole on your Danner's will wear over time. The Foot Tractor Aluminum Bar Replacement Kit will re-vamp your traction and give you the same feel that you had when you took them out of the box. Aluminum bars and screws are lightweight and provide grip when you're walking over slippery rocks and fighting those trophy fish.
