hi, so ive run 1 marathon before and i ran it in light-weight trainers but for my second one im looking to run it in something a little lighter. i have a pair of mizuno revolvers but im afraid they dont have enough cushioning...what kind of shoes should i wear?
You probably should go to a runner's store where the sales people are runners themselves, but that being said, I have a couple possiblities:
Saucony Grid Type A - Not a household name, but I like this shoe a lot and have done some long runs on pavement in them that felt great. They are actually a lightweight trainer, but at 9.1 oz they are plenty light enough for racing and have good cushioning.
Asics Gel Bandito Racer - This is a true racing flat, but not super light as racers go at 7.9 oz. It has suprisingly good cushioning and is another that I have tested on long runs--would not hesitate to wear it in a marathon.
Although I agree with JP on most things, I don't agree that it should necessarily be speed that determines whether or not you should wear a light shoe for long races. I checked your profile and see that you are 5' 8" and weigh only 120. Unless you are injury prone I would worry about whether you can break 3 hours. I often wear flats for everyday running which is usually slower the 8-minute pace just because I'm more comfortable in a light shoe. I wore them in my last marthon (3:09) and am 5'9" 140 lbs. Although I had problems during the last 10k it wasn't with my shoes
