The V-Train's are my 4th pair of Five Fingers and my favorite yet. To address one of the concerns I've seen on the V-Train's, there is more structure to these VFFs than others. However, I have not found that it reduces ground feel or feedback. I do think these needed some additional time to break in due to the structure. The grip on the sole is excellent and well suited for the gym as designed. All in all, I have very happy with these VFFs.
