“River Treads Wading Boots” offer the increasingly popular BOA-closure system that cinches down with a quick twist of a knob, creating a custom fit. These boots are also built to resist the transport of destructive aquatic materials such as Didymo (rock snot) and Whirling Disease. The River Treads are easy to clean, have few seams and are made of materials that dry quickly. Nonporous upper, laces and sole materials also discourage unwanted hitchhikers. To make streamside cleaning easier, Bean included a brush to keep in your vest. The sole is made from grippy Five-Ten rubber, which is also available in a studded version for even greater traction. Whole sizes Medium D 7 to 14 cost $179 for basic, and $199 for studded soles.
