This clearly is the future of gaming, or at least a very important aspect of it. Very reasonably priced and they showed up sooner then I expected. Bought it to hang baseball caps. I had some trouble getting used to using the buttons to change between bluetooth and MP3 modes and the MP3 functions. This measure of the inside length of the shoe, 24 cm, right where the heel curves upward. If you change the string type I?ll purchase more. Easy to replace after owning my pair for over 6years. I can easily pause my music while run, it?s just one tap. The joints are plastic. This is my second pair of Chacos.
