| Running marathon in "flats"
Running a half marathon October 11th. Some people have told me that they feel running that kind of distance is better done with "flats" rather than a typical running shoe. I've always worn Asics and have never had a problem. I have a neutral foot so what is the opinion of all you runners regarding flats for a half or full marathon? Are there any better benefits? I'd like to complete the half in under 90 minutes and was told I could shave 10 seconds off my time wearing flats. HMMM, what do you guys think? |
