High water. Slick bedrock. Cobbles like greased bowling balls. Riverwalkers built their reputation in the most demanding wading conditions, with great flexibility, fast drying times and light weight. Notched flex zones allow for natural foot movement; a polypropylene insole/shank provides stability. But don't let the comfort fool you: these are tough boots for serious wading. Details: synthetic leather and high-filtration polyester mesh (100% recycled) uppers for maximum support, protected lacing, molded EVA midsole; Rockstopper™ insole/shank stabilizes grip and protects against stone-bruising. Extra comfort thanks to the padded insole and ankle support; extra durability from the highly abrasion-resistant toe bumper with stout, reinforced toebox and heel counter. Sized to accommodate neoprene stocking-foot waders.
