As per sizing from this listing, 39 for K. Pan is equal to their 7.5. These fit true to size and they are very comfortable with a manageable heel. Not too high, just right! Came with extra replacement studs and heel caps. As per other reviews, you will need to peel the backing off the bottom of the shoe prior to wearing them....see pictures. Will be back for more colors asap! These were not prime and they came early! What a luxury treat without the major price tag! The pictures are for the nude patent color choice.
