If the shoe came in a size 11. They really are great slippers and well worth the high price point. Well, after 6 months, they havent held up like Vionics. All in all, these are a massive improvement over any tv speakers. As this is my first fluid trainer I don?t quite know how they work internally. - Ohne die eigene Software kann das Ding gar nichts und ist nur Plastikschrott. They?re so cute and keep my feet warm. Well made, very comfy. THIS IS GOOD, b/c If this style of shoe were loose they would fall and slip off your feet constantly since they have a hidden lift. just wish this company would sign a deal with shoes makers and make it in shoes all ready to wear!
