This is the cutest and most comfortable flip flop ever. Keeps a stripping toddler clothed! meaning I could walk outside almost to the end of my driveway without noticing any degradation in audio. They need some time to break in so be patient. Recommended product. Rocks get caught up in the gaps of the waffle like structure. If you bump it, it moves too easy for me. Great item, easy to connect and great quality A+++ Looks nice sitting in the charger. So now they are a bit loose but I can still jog without a problem.
