They are soooo comfy! They are very comfortable since there isnt anything going into you ears. time will tell how long they last. The buttons are intuitive and theyre marked so you dont have to guess or look at the manual to know what each button does. I am very pleased with the overall look and feel of the cover. This shoe is super comfortable and can be worn in almost any setting. They keep your feet extremely warm, are very stylish and can be worn as actual shoes if you are not dealing with precipitation. with bowline knot loops wont come loose ! Great fit, easy access to charge and the wireless charge work even when in the case. They were also more dry than other birkenstocks.
