Bad feet are my specialty, lol! I am hypermobile, have very flat feet, and have Mueller Weiss syndrome (the navicular bone went necrotic and died. Fun.)
Anyway, I had to hang up my normal Ariat Heritage boots. Can’t even walk 20 feet in those without severe pain. I bought a higher quality boot with the cobalt foot bed. The model at the time by Ariat was the Volant, but they’ve moved on to a new style. They are an improvement, but still did not offer as much support as I needed.
The game changer came when my physical therapist recommended Currex insoles. They run $75 online. The company has a quick test to determine which insole is best. I pop those into my tall boots before I ride and the amount of pain in the saddle has greatly decreased, and I can walk around the farm in my boots without as much pain. The company makes many different insoles for various activities, but I bought the ones specifically designed for stability.
Hope that helps.
Now I want to know what stirrups are people with foot pain riding in? I just have normal fillis irons. The bendy flexy ones made my feet hurt worse.
