Great price for chef shoes/nursing shoes! It allows for various functions, keystrokes, and macros to be assigned to the buttons. I bought these for my daughter birthday and she love them great fit. I just received my new one in the mail and it is without flaw! I had owned a pair of Crocs before so I knew they?d be comfortable, but I didn?t know what to expect out of these ?work? shoes seeing as the design was different from the traditional/original pair of Crocs (the ones with an adjustable heel strap), and in my opinion, more aesthetically pleasing to the eyes. I had hoped to use this product for outdoor bike riding since these headphones do not cover your ear. Looks handsome too! The thing with Brainwavz is their large variability in product quality. Use the old tread pattern or sole composition. tutto ok !
