3 types of running shoes?

Im a bit worried about my feet in the long term here.


I wear Nike Free v5.0 for my normal 4 day a week runs. They are usually 3-4 miles at a 8m/m pace. These shoes offer no support or control on the heel. They are the 'barefoot shoe' I have been using this style for about 5 years now.





I wear Nike Shocks for my sprint days since they offer a ton more support then the Frees. I only work on sprints 1 day a week, normally on a track type surface or blacktop.





For the Army I have to wear my boots during most PT, which could be on any type of surface.





Im working hard now to get ready for SFAS and Im a bit concerned about the condition of my feet. Anyone have any info / advice?

If you aren't having any pain (foot, knee, back, etc) then you are probably ok now. You can always check with a doctor (or better yet a sports medicine specialist) about getting insols that fit your needs as a runner.
