Can I re-enlist with RE 3 and separation code JFW for flat feet?

Boy, times have changed. I went down to Fort Hamilton for my draft physical (Nov 71), with a doctors file covering my flat feet and fallen arches (trying for 4F, to not get drafted). At the end of the physical, to include an ortho consult, I was told I was fit for duty and that a profile for my feet would be waiting for me at basic (Fort Dix). Never saw the medical profile, which actually turned out to a good thing. Went through like everybody else.
Later on, I got some custom inserts at Valley Forge General Hospital when I was TDY there in support of the returning Vietnam POWs sent there (early 1973). I wore those plastic inserts for 15- 20 years. Still have them in my “military storage tote”.

Sorry, but that brings back a funny story. I was wearing those inserts in my books during a night patrol/attack in advance ROTC camp at Fort Bragg. We were moving quietly through a wooded area when the TAC officer stops and says “what the hell is that noise?” After resuming our approach, he stops us again, and comes up to me and says, “Turk, what’s with your boots?” Turns out the plastic inserts were rubbing up against the leather, making a noise. The inserts came out on the spot and I never wore them again on training or noise sensitive missions.

Hmm, I’ve had flat feet all my life. I may have a very little arch. My wife calls them “chicklet feet” (check out chicklet gum). The point is I enlisted in the Army in 1978. The only time I had problems in BCT was after very long road marches, and Ft Jackson in August is hot!
The point is that I served for a total of 21+ years, in two different services. So it is possible.
My father-in-law wanted to join the Navy in the early 50’s, but they wouldn’t take him because of his flat feet. Mind you, he was a runner. He went next door to the Air Force recruiter, and guess what? He enlisted in the Air Force.
Don’t put all your eggs in one basket. Check out the other services. You might get a break.

They’re doing this again? When I joined in 2002 my flat feet was a non issue. I got custom orthotics and got sent to basic. 17 years later, I still have no issues. It was my understanding flat feet went out the door as an issue decades ago.
