I am going to be running my first ever marathon in 3 weeks. I currently own some Saucony Type A3 flats that I wear for intervals/tempos/races. I have run up to a half marathon in them and they felt okay. I plan on running about a 2:35 marathon. My question is, has anyone tried the Type A3 shoes in a marathon and if so how do they hold up? Did your feet feel okay after or did they hurt? Thanks in advance.
