These shoes hurt when putting them on, my husband had to heat them up a bit so he could stretch them out so that I could put them on with out the upper part of the plastic cutting into my skin and hurting me. Needless to say they are not my favorite shoes go lol. The red and the black ones fit just fine, abandoned they were made by the same company, so I have no idea. If you're going to buy these you really need to go a whole size up, because they do run small.
