So, I've had surgery on both feet. The doctor fused the transverse tarsal joint in both feet. So now I still don't have pronounced arches, but I do have a slight arch in my feet now. You can see the arches more on x-rays, as my feet still look flat but now my knees naturally point outward, instead of pointing in. Anyway, I need to learn to squat again. I'm looking for the best exercises that I can use for my body to re-learn the squat potion and strengthen the small muscles. The doctor told me I need to workout and walk in order to reduce swelling in my feet. He actually told me to go and lift. Also I did some body weight box squats today and my knees felt tight. I put on knee sleeves and that actually made my left knee hurt.
