I've been feeling restless because I haven't run since last Thursday so I headed out today for an easy 4-1/2 miles. It felt great to get out. The Vibrams have held up pretty well after 16 months of use. I don't keep track of my miles so I have no idea how many they've done. If I was to use the Texas Official Scale of Measurements then I'd say it was a shitload.
Overall the wear patterns are pretty symmetrical except for my right heal. It has more wear than my left heel. Curious, I checked my soles. The skin on my right heel is thicker than the skin on my left heel. Whatever I'm doing wrong, I'm being consistent about it.
