I bought my Vibra FiveFingers KSO Black in March 2010 and I have used them ever since on all training and running events. In the winter, I have used a pair of ”normal” shoes with spikes. I have no statistics on the KSO, but my guess is I ran about 1200 kilometers in them. But no more. In the latest running event, Midnattsloppet, they fell apart – two seams and the rubber on one toe. So, I had to throw them away today.
I have to find a replacement pair soon, my KSO Trek isn’t as slick and comfy as my old KSO.
