Get traction on your foot braces by wearing the Astral Limited Edition Rassler 2. 0. Whether you need the traction to help you navigate through rapids or to give you more grip for a stronger stroke in flat water, the Rassler 2. 0 has a G. ss rubber sole that won't slip as things get wet. This shoe is designed to drain and dry quickly when you get to shore, and uses Balanced Geometry (with minimal drop) to provide maximum agility while portaging. Astral gave the Rassler 2. 0 a Polygiene-treated lining to help it resist odor buildup, so you can enjoy stepping into a dry, fresh shoe before each day in your boat.
