I've been using these for four months already, and they still give me painful blisters on the insteps of my feet, and on longer runs, at the tips of my big toes. Sometimes I have to stop halfway through my run because they hurt so badly. The issue seems to be the seams that are located right at the instep - a terrible location, since that's a pretty sensitive part of the foot. I've already got some minor calluses developing there now, but it's going to take them a while to build up (from nothing) to the point where I no longer get blisters.

I would have returned them, but I had ordered them during a brief visit to the U.S. from abroad, so I didn't get the chance.

My previous pair of Vibrams, which I loved, were the Bikila Evos, which I ran in almost daily for three years before the seams gave out. These V-Runs were supposed to be a step up, but I'd say they're a step down. The material is lighter, but it feels cheaper, and the design definitely isn't ideal for people with average-width feet.

I hope Vibram can fix these issues in the next version of Bikila or V-Run.
