I have flat feet and overpronation. As a kid, I used steel shoes to fix it, kinda like Forest Gump. Also used custom made hard insoles. The ones that requires you to walk on some digital band and film your foot. Soft generic (quality) ones work better for me so currently using those with wide soft running shoes. Anything of Nike is too narrow for me, just to give you an idea.
If I try to walk as fast as the average person, my feet basically gets cancelled after 1km. Front muscles below my knees turn into rock. I lose flexibility and ability to move my ankle. Its also painful. I broke my right foot in past and walked 0.5km on it and the pain is similar.
Even if I walk slowly, I can't walk more than 5km in a day. It takes 2 days for the pain to go away. When I sit somewhere to take a break, it doesn't just go away. Its a weird kind of pain. Kind of subtle but more impactful.
As a result, I cannot enjoy any social interaction that require me to use my foot on that day. Its also extremely rare for me to enjoy any sight seeing. I've been to some of the world's most popular tourist attractions but I couldn't enjoy them. I also sweat A LOT on foot, which I'm guessing due to discomfort.
When I fly, my feet usually get cancelled for a day because of the walk in airports.
I watch backpacker Youtubers and I envy them a lot. If I could walk 10km a day without pain my life would get unimaginably better even if I wasn't traveling.
Surgery for this takes a year to recover, you become dependent on others until recovery and it also has risks. I'm scared of ending up in a permanent wheelchair and I live solo so this doesn't seem like a good option.
Anyone here who's similar to me who's able to enjoy their travels? Any tips? Any doctors or information sources you can recommend?
