I'm looking for a good marathon running shoe recommendation. Currently, I'm running in the ASICS Gel-DS trainer 16, and I really like the feel of them, but I also feel like they are too light to get me through my full marathon this fall (I've used them for a few halfs). I don't want something TOO much heavier (current sneakers are 8.5oz), but possibly looking to switch to a different brand of sneaker.
About me: I am light (~105 lbs) and small, female. I generally go for a "stability" shoe, I do not overpronate or need extra support. I'm aiming for a 3:30 marathon this fall, I run a 1:35-1:40 half marathon.
