These shoes were pretty tight when I first got them but after about a month of casual wear they are slowly breaking in. I wear a size 10 1/2 and I bought an 11. The leather is pretty heavy duty and thick in the upper. It will take time for them to stretch and loosen but I can see them becoming a favorite sandal. I do wish the material your feet are on was not so fabric like. It is starting to hold odor after a month. I will return to update after more wear.
