I started running again in about December 09 after a 10 year plus hiatus. By January, I was already miserable from shin splints among other pains. After quite a bit of research, I went to Phillip Galls outdoor shop in Lexington, Ky. and tried out some Vibram Sprints. Debated on it for a couple of hours, went back, and they were sold out of every size. Checked the website and finally got a pair of KSOs in a week later (glad I went for those in retrospect). May have picked the coldest time possible to start something new as well.
