Cute shoes, daughter (7) said they were comfortable. Also, where the pieces of leather are sewn together, the threads may eventually give way. Reordered the 2-3 and they will work well for her. Other brand options are the UE Boom which has better battery life and similar sound, but the X3 has more potential and higher output. 5, but all that was left in the color I wanted (white) was out of stock, so I went with a size 7 and theyre perfect! Very comfortable fit even after long periods of usage. And does it well! If youre replacing OEM rails its not a big deal, as you can just use the Torx bolts from your old and busted rails with these new ones, no problem. They make all the difference in sound quality, and when they wear out I will definitelly order again. Great decision.
