This was on my son's wish list. I made an order and had it mailed directly to him along with a couple other item on his Amazon wish list. It took a while to actually find a size 12 listed and I was so excited! My son wears 12 but when he received these, he loved them but they were too tight. He wanted to keep them and try to stretch them because the boots had been on his wishlist for about a year. Amazon did not have a size 13. I search the web and did find a size 13 on ebay so my son is sending the 12's back. I read other reviews about Diesel boots and they seem to run small.
