The shoes is extremely comfortable, I am truly delighted. I can imagine running in it, it is that comfortable and I have wide and tiny feet. I just got it today, so I can't comment on the durability of the straps and buckle. The buckle as commented by other buyers is easy to slip on and slip off.
The other comment is the shoes have a lot of straps, so it makes the feet look bigger and the ankle look wider if this is your concern.
The only (big) disappointment is the color is a dull very dark blue, close to black, not like the transluscent light blue color as shown. I cannot imgine the shoes ever be that color. If it was as shown like the web, it would have been a perfect purchase.
