I bought these to replace my Keen Newports after years of faithful service. I had my phone in my room and went to the living room and didn?t even notice the difference. I have to wear high socks. Remember when Tom Hanks character in the Green Mile was able to pee for the first time after being cured? It was like that. It folds easily so I can hang it out of the way. Shipping took about two weeks, but these shoes did come in great condition without issue. I have numerous medical problems with my feet and find it difficult to find shoes to fit. Nike changed the material for the comfort sandals & in my opinion, dropped the ball. Die App hat jedoch funktioniert und die Kopfhörer erkannt. Sound quality is the same, if not better than the microphone I had before!
