Saguaro Brave I size 41 with flaws. They are barefoot shoes. They have no arch support, no heels and the soles are thin and flexible. They are waterproof. There’s a membrane. I put them under running water for a few minutes and the inside stayed dry. I didn’t test them in the rain. They are brand new but defected. The insoles are folded at the front edge. There’s a gap on the inside edge of the right shoe. I circled it on the photo. Also some wrinkles on the left shoe. The insoles measured 26.5cm x 9.5cm. If you have narrow feet and replace the insoles, I think they are still wearable.
