BUY ONE SIZE UP THAN YOUR SHOE SIZE. no, it's safer to just buy my normal size, right? NOT RIGHT. I'm a size 9, I bought a size 9. These things are 8th magnitude at best. I need at least a size 10. I gave them to my wife who has smaller feet and even she complains that they are too tight. Be prepared for a break-in period. The woman's legs are covered with blisters. BE WARNED.
