Perfect lightweight barefoot watersport shoe

I'm a paddleboard instructor and I absolutely love these! Ideal for taking with me on the board; easy to slip on and off for portaging, and I can even run in them. These will be my favourite summer shoe 🤟🤟

Best Lightweight Camping Shoes

As an ultra-light backpacker, I was looking for the lightest alternative to Crocs for camp shoes, while also functioning as wet shoes for river crossings.

Safe to say the ultra 3 meets the bill!

Size is a bit larger than what I'm used to, but that's also because I go barefoot in these, so without socks, your shoe size goes down half a size.

Overall, sturdy and worth the investment!
