I've been wearing these in rotation with other shoes since around September. There's no major dirt, and they're not worn out. However, there is some minor dirt, so please check the photos. The FILA letters light up on both sides, but only the bottom part of the F on the right foot no longer lights up. The top part lights up, so it looks like it's glowing overall ☺︎ They're very cute, and my daughter loved them. They seem to be 14cm, but perhaps because they're slip-on, they feel a little small. I think they'd be good for a 13cm child ★ My daughter wore them when she was 13-14cm! They're not Velcro, but my 2.5-year-old daughter could put them on and take them off by herself without any problems. They've been home-cleaned. They will be shipped compactly. #itobaby
