Really love these shoes. I have tried so many and finally I got 3 on the Prime Wardrobe to try and kept this one!
Prime wardrobe is the bomb! I love that service for prime members!
I usually wear 7 1/2M and the recommended size is 7 1/2 and that is what I bought. There is enough room at the front of the toes (the "thumb test")
Even with thick socks, I have plenty of room in the toe box and the front of the shoes so my toes do not feel jammed at the front..Toe box is wide enough and the arch support is adequate for me.
I have used these whenever I go for my walks but I have not tested the waterproof quality yet.
I'm going for a hiking trip this summer, so may give an update on this.
