My Vapor Fly 4%s just arrived. They feel fantastic out of the box. Noticeably different than the Zoom Flys. My question is how to best to use them? My initial reaction is to only using them for races. The thought of racing in a shoe that I haven't worked out in makes me a tad uncomfortable.
Should I use them for a few workouts here and there to adjust before races?
Should I only use them for races?
Should I cash out my kids' college funds and wear them everyday?
Trolls - Should I through them in a dumpster fire?
