The Patagonia foot tractor wading boot is one of the best winter and cool water wadding boots on the market. It has a heavy bottom with a very grippy rubber sole. This allows you to keep traction in the slipperiest conditions. I have personally been using the foot tractors for about four months now and have been very happy with them. They keep your foot nice and warm even in freezing water. They provide amazing ankle support and don’t allow your foot to move and shift in the boot. I have found this most helpful when standing on slanted and slick rocks and other river obstacles. This is an amazing and very durable boot.
