I did a whitewater rafting trip in Patagonia that included lots of canyoneering and climbing through slot canyons - apologies for the humblebrag....
The guides instructed us to get the shoes linked below and not to vary from them - get exactly these shoes.
They were spot on. They were perfect for that trip and I've used them for wet wading since. The shoes provide better traction than I've ever gotten with felt or studded wader boots. I've had them for a years now and they have held up, drain really well and are very comfortable.
