Dr. Martens Black Chelsea Boots

Bought these 2976 Platform Chelsea Boots in store at $279.99+ tax and thought that I could stretch them after wearing them; but they are far too tight for my feet (a true size 9). I have only worn them out twice for short outings. I would recommend these boots for a size 8-8.5 US or a very narrow size 9 US. I'll post some real time pictures of them when I have access to them.
