I have been toying with trying some zero drop shoes, namely Altra's. People I know have been wearing and raving about them. I'm currently in MT110's, Go Run2's, and Pure Connects, all of which have the 4mm drop (I think, maybe the Brooks is more).
How will my feet do in the zero drop? Is it enough to be running comfortably in the 4mm drop to make the last drop? (at least for one pair in the rotation?)
4mm has been good to me so far. not really looking to minimize more, just mix it up a bit.
