I run 40 miles a week and wanted to build up my leg strength. So I decided the best way to do this was to get my first pair of Vibram, these V-Run. My first run was on the treadmill for 8 miles. I had to stop cause I was getting a blister on the bottom of my feet. I loved them still cause the shoes made me switch up my run to land more flat footed. This is what you want as a long distance runner and I was happy with that. I wear Injinji toe socks everytime I run in these and everytime I get a blister. It's painful and I have to take 2 days off from the long distance on the treadmill. I can't take it anymore and my patience is done. I don't get the blisters between the toes that others have said. As far as fit, they fit perfect. I usually wear a size 8.5-9 but I went with the size 42 (Size 9 US) because you want at least an extra .5 inch for running shoes and they fit like a glove. I have no complaints about the shoe because I really like the look and fit but the blisters on the bottom of my foot is too much. Also, I notice the bottom of the shoes get really hot. Not sure if anyone else notice that also but I suggest either a thicker sole or something to negate the heat at the bottom of the shoe.
