"After a few months, I started wearing shoes without arch supports to force my feet to adapt. Managed to get rid of my foot pain within 2 months :)." This demonstrates a truism that we should all become familiar with: If you brace a body part, the body part being braced will become weaker. Orthotics are a brace that hold up the arch of your foot. Your arch will get weaker. "Sprinting any amount hurts, and I have to avoid all hills (going up is fine, the descent is killer)." I cringe to offer up personal anecdotes or helpful tips, but on the outside chance that it is helpful, you might try running downhill on toes only - no heel at all. It's a bit odd looking, but it's worth playing with.
