I get pain on the top of my right foot if I hike too far, extending into my ankle. Working to strengthen my ankles has helped–I no longer have my right ankle collapse underneath me when I am tired, resulting in far fewer falls. Wearing more minimalist shoes have definitely helped as well, I am far more comfortable with more flexible footwear. These days, I mostly hike in Inov-8 boots. I wear Merrell Barefoot Jungle Mocs with 0 mm drop for my everyday shoes, but have yet to make the transition in my hiking footwear–$$$, boots need to wear out first.
I have started using Barefoot Science footbeds, which have progressively higher inserts that promote raising the arch, according to company claims. I have seen them recommended on Brian Green's blog, and I think that Damien Tougas recommended them to Brian Green. My feet have been adapting pretty quickly, but I have a couple of problems that I'm trying to wrap my head around.
Flat arches are caused by weak feet, aren't they? So, how does an appliance help strengthen my feet? Wouldn't I have to be doing exercises of some sort? How do I know how "high" my arches are supposed to be? If it is the appliance that does the job, don't I have to wear them always, or my arches will fall down again? The little bullets of high density foam that are inserted under the footbed do collapse somewhat, so over time you'd have to replace then, or the foot bed is useless. And, minimalist shoes make a point of not having arch support, so how do barefoot hikers not have flat arches, if we all need some support?
I'm not relying only on the footbeds, I'm also doing some "foot yoga" to separate my toes and allow my feet to spread and move better. I'm trying to decide whether or not to purchase any more of these footbeds, or if they are only promoting more unhealthy habits
