The lesson is, do not buy any footwear online! I like my other Icyzone clothes and overall Id keep these, just not sure how the looseness in the knees will effect comfort during running or yoga. This product is insane. The build quality is pretty good, the earpieces are well padded and comfortable, adjustment is fairly easy, the audio is fine, the volume controls are simple, the microphone works well, etc. Screen protector did not work with fingerprint. I finally have a place for all of my spices and clear up my cabinet. no pressure on the top of my foot and they are nice and comfy :)All the best, Take care and stay safe. This is my second set of Cobian flip flops. It?s light weight and a nice soft material that provides nice warmth without adding a lot of weight. This is a very compact rugged camera that is easy to set up and use.
