I'm going for sub-2:40 at new york. I have to run in Nike's. I can't run in flats, because of achilles problems. So, I need shoes with a normal size heel. I usually run in skylons, but they're out of stock at most places now. Road Explosion 2's are lighter, at about 8 oz. I have very little money, so I need cheap shoes.
Recommendations? Sites other than the obvious? Shoes that would be lighter than the 11 oz or so skylons? Can you run a marathon in the road explosion? I'm posting this only after spending hours trying to find the skylons in size 11 or 10.5 and having little luck with the road explosion 2's.
