I recently invested in the NRS Kicker Remix Water Shoe that's sold by REI, and I absolutely LOVE THEM!
I often find myself kayaking in lakes/rivers with rocky bottoms, and have found that the solid and grippy sole works extremely well on slippery surfaces. Another great bonus about these shoes is that they cinch around the ankles, so you don't have to worry about them coming off. Their design also "reflects" your foot's heat back on itself, so even if you're in cold water, I have found that these shoes keep my feet nice and warm!
This isn't entirely designed like a regular sneaker, but it works great on land nonetheless!
one or more gifts or other benefits from the co-op.
