I tried the Vibram Five Fingers running shoes (they're basically like gloves for your feet - thin nylon fabric, no sole, grippy little lines and dots on the bottom for traction, and of course, individual pockets for each toe). I took the salespersons advice and walked around in the house for a few hours a day for a week to let my feet adjust. Tonight, I tried them on the treadmill at the gym. They take some getting used to - my stride felt awkward for the first few minutes and my feet didn't feel very comfortable, but after a short time, everything seemed to click into place. The only noticeable difference was that my hamstrings felt like they were being stretched more. I'll have to see how I feel in the morning, though.
Has anyone else tried these "shoes"? I'd like to hear about your experience with them.
