I saw these and I read the reviews and said why not. I am very please with these and they even sound better if you pair them with a DAC! Ive seen other reviews that mention that one boot had loose grain while the other was fine, so maybe this is a result of poor quality control. I wear size 9 womans for most brands and a 40 for European sizing. Pero no hay ningún problema con el producto. 5 to a 11 and I purchased a 10 in these shoes and he still has a little room to grow. Strangely, if you create the low frequencies yourself (like snorting, for example), it seems to actually amplify those sounds and the speakers will distort horribly. I wish shoe companies would consider that women with larger feet like pretty feminine shoes in pretty colors also, and when sizes run pass an eleven theres only black, brown, and gray Fila please make a difference. Besides, it had umpteen feet of extra cabling that I did not need for this purpose. Then, of course, they get washed, stepped on or stolen by one of her headphone fiend friends--- and Im the one left stuck out.
