I got out for my first BF run of the year a couple days ago when we got a flash of spring with temps in the mid 70's. I've been doing my runs in Vibrams, and doing my best avoid road salt -my feet's nemesis. I only did a little over a mile BF, and stopped to put on my shoes as a matter of planning rather than necessity. The rest of the 4.5 miles was just gliding fun.
