new bindings, they are really tight - 2005 3DS

So, I just got a new pair of Medium 2005 3DS bindings. I spent some time with shaving cream in the bathtub and I finally got my foot in. Holy crap they were tight. My foot was turning white, so I decided to try and pull out...yea, that was chore.

So, did I buy bindings that are too small? Or should I do something to stretch them out?

I wear between a 9-9.5 shoe. My feet are probably a little bit on the wide side...I'm a 9 in length but most 9 sizes are to cramped for me.

Thanks
