5 def go for 6 I am a 5 and they fit perfect. They are also padded just enough in the sole so I feel comfy but dont slide off the sole. Send them back straightaway. I also recommend the mod kit as it works great for reducing noise, but it isnt as comfortable over long periods of time. So now I am in my basement, on my computer, my feet are comfy, and most important safe. Fit is small and strap is tight around/on toes. In terms of comparable quality, I would say they are slightly better than Dollar Store headphones, but not by much. Cutting my hands off wasnt a very sound idea so I went onto amazon and purchased these bad boys! Beautiful surface, well polished without any sharp edges. Over all I like this product but it would have been better if it had a towel stop or a curl on the end to keep the towel from sliding off.
