HiyakAstral's Hiyak water shoe is their version of a "proper" river booty a lightweight, quick drying, high top river shoe that provides excellent stability and insulation without using neoprene. Super grippy G Rubber makes for great traction on slippery, moss covered rocks while the high top padded ankle gives support if your foot rolls. Maximized surface area and Razor Siping on the sole for high friction and edges that bite into sketchy terrain.
