I recommend cloud foam inside in these shoes because of getting me feel on cloud. Was nervous purchasing this due to mixed reviews. brought for my 15 year old for Christmas, So she’s only had these for a month and takes two ballet classes a week. Unfortunately the size 6 is too big, but the 5. and so I think it’ll frustrate the average user with its limited size. Puede que este ante una imitacion, todo fue muy raro, la caja tenia el sello abierto, el tapon (primera foto) debe tener un numero y un codigo QR y no trae nada, checando en internet, todas traen y esta no. I get the pink color and It is really cute. The double tap features to play and pause, the answer and hang up calls. I mean I will use these for hours a day for like 2 weeks in a row before even thinking about charging them. Wifi/Mobile data/BlueTooth and GPS all work well and i havent experienced any problems so far.
