The kickstand fit perfect on my son?s Trek bike. I was testing them out with my chop saw and vacuum it was really cool I could jam out. 99 on 50 pages. what a bad design. I will absolutely be buying at least 4 more pair! Running 20-50 miles a week depending on my goals throughout the year. good microphone even when outside. I got em in the next day and was so busy I never had time to test em out. Otherwise I love the feel of these slippers and just ordered another pair. I am returning for another try and will see if I get a good one.
