Adds a very finished and sophisticated touch to the look of the room. I would say the reason for this is they are using the shoes for high-activity sports that put a lot of stress on the arch. The K371 went too far, imo, I *tried* to like them, but I got a headache from the low end every time I tried. Really cosy and a very cute design. They aren?t cheap, and so this is very disappointing as it appears that the standards have significantly dropped. My first pair of chaco sandals, and I know it wont be the last. The pump it comes with isn?t necessary. The quality is a joke. The earphones sit on either side of the charging station and theres even a charge level meter thatll tell you how much power is left in the earbuds. Build quality seems alright.
