I was worried when I bought these online since I am a men's size 11 and the only options were 10-11 or 12-13. I ordered the 10-11 and they fit comfortably. These are awesome. If you are already 6 feet tall, they make you feel 10 feet tall (6-5 in actuality). They are perfect for my Herman Munster costume (also purchased on Amazon). One caveat: Be careful, especially if you are not used to wearing platform shoes. Even though the boots have a zip top, it is very easy to step on them wrong and twist your ankle. I would practice walking around in these things before wearing them to a party. You might look odd wearing them at work or the grocery store, but what the heck? have fun with them.
