Flat Feet and SFAS

[AtAllCosts]

Short version: I'd like to hear your experiences with flat feet and plantar fasciitis and how/if you managed any and all of it.

Long Version: I went to Podiatry today (the only snag in my SFAS physical) where I was told that my right foot is extremely flat, causing weakness in the ankle, and as a result, run a severe disadvantage and slight risk if I want to attend SFAS. I'm fine with a disadvantage, people with flat feet get selected all the time I'm sure. But I'd like to hear ways I could possibly minimize risk of injury and as work on pain management if at all possible.

I've been prescribed custom orthotics, but the Doc was sort of a downer, saying while it wouldn't really help, it would keep it from getting worse. However, he did say he was going to do everything he could to help and even ordered a CT scan to get a better look. Nonetheless, I appreciate his overall medical expertise.

I have a feeling I'm going to end up sucking it up and dealing with it, which is fine.

Anyway, back on track. Have you known anyone with flat feet issues bad enough to affect the way they ruck/run? How did they manage it? Any tips?

Thanks for your time, gentleman.
