" Shoes should be silent. These are a dream. I would size up for a comfortable fit. These are nice but run small. Will update if I receive the end cap. The earbuds are simple and comfortable. Dual channel. The charging case appears to be well constructed and designed, and the earbuds always automatically turn on when I remove them from the case. I was stoked when I found this one and I have not been disappointed. No running in them your child can slip but they still have the hard bottom.
