Astral Loyak water shoes provide the right combination of traction flexibility and durability which we need when traveling on a raft or kayaking on technical rivers. Stitched Cordura upper is highly abrasion resistant durability but at the same time it allows air to pass through and dries quickly. The upper is also attached directly to the rubber outsole for a low-profile fit and improved underfoot feel. Rubber G. 15 helps us maintain balance on slippery river beds and slippery rocks and the flexible grooves allow our foot to bend naturally.
