These shoes are terrific!!! I wear a size 14 and they fit to a tee. They could be worn all day without a problem. If you are a mens 11 1/2 or size 12 the size 14 is a perfect fit. Unlike heels that are over 4 inches, these 4 inch heels are very easy to walk in. The big plus is the heel is very strong and supports easily 195 lbs.
