Barefoot shoes are the best way to go in the long run for every one it makes everything more natural.
It is worth remembering that you shouldn’t jump straight into using them. Start by reducing the drop on the shoes you wear and build up to wearing barefoot slowly so your body can adjust to them. I’m in the process of moving into barefoot for running.
As it’s for medical reasons I would seek the advice of a professional, maybe a few professionals to get a well informed answer. Remember what works for 1 person will not always work for another.
