This booth 9D my is 8or 81/2 , they don't have 8 1/2 only 8D &9D from that I think 91/2 which  to me that doesnt make no sense I may be wrong .
 I feel a lot of space inside with my boots but I put on a thick socks That did the trick but I have a lot of movements , but overall the boots did his job keep my feet warm and that was important
