These soles are flat and the shoe is extremely stiff. I especially like the fact that it is able to adapt to any plug style and any plug can go into it. That being said, it connects via USB type C so having the option to use your own cable is a boon all of its own. Pero variaban muchísimo en otros lugares la veía hasta el triple de precio, entonces busca lo que mejor te convenga. I guess I can use them for something but, buyer beware. I wanted to connect my Blue Yeti microphone to my Android Phone to record YouTube videos with good sound quality. I have a nerve problem in my foot they were so comfortable I ordered a black pair and the snake looking ones. The biggest issue for me is the shoulder area kinda weighs down the rest. Theyre "too quiet," "muffled," "weird," and "unnatural sounding" compared with the Q20. I think they will stretch a little bit, as most sandals do.
