As a more heafty sized woman, my feet aren?t narrow and light like other women?s feet. After you put it on you cant use the ball unless you remove the bike carrier. Llegó en excelentes condiciones y es nuevo. Update: I gave my daughter the size 6, since she wears a size 7, and it fits like a 7. Nothing worse than a sloppy slipper. The colors are very nice - I personally love the darker slimmer colors. They worked fast and communicated quickly to make sure that my daughter had her present for Christmas Day! easy for anyone to do. They are super cute and comfortable. No need to worry it came in a immaculate condition and im so please to give it as a gift.
