5 and I think the 7. This hasnt been an issue so far, but I wont travel with this mouse. now it fits my ankle bone. 5 N and they fit much better. The soles have become completely unglued from the rest of the shoe, and the rubber section (where the foot actually rests) has shrunk by a few inches at least compared to its original size. Awesome purchase. Goes on easy and comes off easy. I can recommend this product as well made and if it matters to you it looks the business as well, worth the money for me. or ask here. Love this sneaker hope they never discontinue them
