The NRS paddle shoe is one of my go to pieces of paddling equipment. When I paddle for any length of time without them my heal gets sore without the cushioning effect of the neoprene, Additionally, the sole is substantial enough that they allow me to walk around on uneven ground as I move my kayak from place to place or walk back and forth from my car to kayak as I load it. Great shoe and great design. The only downside to the paddle shoes is they get pretty stinky when I'm doing a trip and I have them on my feet for days at a time, and the zipper of one them has gotten a little finicky; it still works fine, it just takes a bit to finally get it to unzip from time to time.
Overall the Shuna just feels good in the hand and was a delight to paddle today. Glad I bought it!
