Im certain Ive spent more time trying to get the dock to function that I have actually using the device as it was meant. It so smooth. Lightweight with everything included for the boat I always wear crocs around the house as I have plantar fasciitis so have to wear something otherwise I’m in pain. Since they arrived three days ago, Ive worn them every day all day, including long speed walks (an hour or more), no blisters. Battery lasts a lot. I’m a sound engineer so I’m really picky about quality and these are just flat out great. And these are my first crocs I have ever bought dont care for the the fat feet look. Some people ask, why not just add music to your phone? (oneplus 6t) thats because phones are heavy especially when youre doing activities like exercising. Extremely comfortable
