Considering the build quality of the rest of the headset, Im thinking AT added this (and the mic-mute) at the last minute. My feet didn?t get sweaty. The thin foam on the earpieces doesnt provide enough padding for long-duration sessions (1 hr max for me). They fit and look fantastic I know that Merrells argument is that they dont want somebody to be injured by a defective shoe, but come on! Super non slip too! )I bought these as house shoes. I am making them as fast as I can, the results FAR exceeded my expectations! T MOBILE, VERIZON, ATT. WeelerChaco presents many images to the people around him.
