Suddenly wondered this morning how I was going to attach my time-registration chip to my Vibrams without the help of shoelaces. It actually wasn't such a problem as the strap fits exactly through the spaces. Took it out for a test run this evening and found that after about half an hour there was a point that had made a tiny scrape on my foot where it rubbed the skin. (The visible scratches are from yesterday's run, nothing to do with the chip.) Stopped off at Carin's to get a plaster for it and ran back just in time before it was completely dark.
