I have several! My 3 year old daughter wears a 8c. ¡Excelentes! My sport had as much comfort and arch support as the over priced Reef. Construction quality of the speaker is pretty good. I like really loud music, but it kind of gave me a headache. There are 2. Because this speaker is GREAT! I?m happy with it, but for the quality, it?s definitely something that should really be in the $30 range. The good: Great battery life, large screen, good cameras, smooth UI, very quick.
