After a three week break due to work and a vacation I finally got back to running the other day with an early morning 5 mile run. Felt pretty good although I was taking it easy with 9.5 min/mile. Until recently all my barefoot running has been done in warm, hot or blazingly hot weather. This last early morning run temperatures were down in the 40's (Fahrenheit) and the only part of me that was cold were my toes.
This is going to be a problem when the really cold weather kicks in so I finally broke down and purchased some minimalist running shoes to be used in cold weather.
After some research I ended up purchasing a pair of Vibram FiveFingers Bikala.
