I have not used the sneakers for anything other than walking 5 miles a day for 2 months.  My right sneaker has finally given out.  Both the front and back pads have tears in them and deflate every time I take a step.  For 100 dollars, I expected the shoe to be of better quality.  I spent half that in another pair and other than the sole being worn, it is still in tact.  Please don't give into the hype, it's not really noticeable.
