I have a MS aged daughter who runs the 400 800 1500 but I'm primarily looking for a racing shoe that she can use for the 800 1500 that will allow her to compete well but comfortably and safely.
You can assume that while I run a little myself I have never been a competitive runner and don't have a clue about racing shoes, flats etc. She is training (and still racing) with Saucony Women's Virratas at 800m distance. She has a pair of Rocketgirls that she runs 400 with but isn't interested in them for the 800 and I haven't suggested she try them at longer distances.
