I ordered a 10 and they fit like a glove. I actually like them a lot more than I expected to. fu7712 adidas UPDATE: Im finally not very surprised to see that after a few weeks (under a month), my unit stopped working. I suggest buying the 3 pack cause it seems as if its purposely designed to be a faulty product. fu7712 adidas My confidence is shaken in this unit. fu7712 adidas Well constructed and durable. Product fit as we hoped for. Please stay away from this product fu7712 adidas I removed the insole and the flat foot bed didnt relieve any pain. My 6 year old wears a size 3 1/2, so I bought this a bit bigger as she’s growing.
