Edit after a month. Otherwise its all good. I was told to pair it with a new device each time it becomes undercoverable. I bought these to pair with my iphone 11pro and they work great! These shoes are the most comfortable thing I have worn since my pain progressed, and they are ADORABLE. Jamais vu ça! The ones they sell at best buy or similar are terrible - catalyst - overpriced. I?m overall unhappy, disappointed, and will sadly return these. The Soles are some kind of cheap foam that wears waaaaay too fast! Also the 2 halves don?t stay together well.
