This will be my third pair of the KSO's in about 1.5 years. After 6 months I pretty consistently get a hole in the toe.

My usage: 5 day a week weight lifting. 1-2 mile runs 3-6 times a week. 1 mile walks 4-7 times a week. So, very heavy  use.

The good: These seemed to have cured my plantar fasciitis that I got walking around Europe in boots. When I switch over to running in Nike frees, they feel insanely heavy. Maybe placebo but it feels like I can run faster in my Vibrams (when doing HIIT).

The bad: The biggest issue of course is the hole on the sole. Also, despite using some anti bacterial shoe powder, they start to smell pretty bad around the 5 month mark.

Overall: Despite having to order new Vibrams every 6 months, I continue to use them.
