Most of our meets are on a track that is a little weathered in lane 1 due to all the spikes and a lot of use. For some reason I almost always run faster on other tracks that are in better shape. I've seen some kids using Vaporflys for the 3200 instead of Dragonflys, which is what I wear. Is it ok to use the VF for the 3200? I also like that it will give more support, since I tend to be a little injury prone.
