Wading on slippery river rocks, often referred to as bowling balls, can be a challenge for even the most seasoned fly fisherman. Which is why Patagonia created their Foot Tractor Wading Boots with aluminum traction bars to provide grip on a variety of slippery surfaces. Unlike felt soles which provide grip, but can also transport invasive species, and traditional studs which are virtually unwearable in a float boat, the Foot Tractor Wading Boots provide consistent traction without any downside. Oversized heel and toe cups not only protect feet while wading or hiking, but also add durability to these men's wading boots. A Clarino synthetic leather upper delivers lightweight support and monofilament mesh drains water quickly when you step on the river bank. Anglers looking for a multi-directional traction option as an alternative to felt or traditional studs will appreciate the technologically advanced Patagonia Foot Tractor Wading Boots.
