With the bow and arrow action of the foot and all the movements it takes to achieve that spring, shoes can inhibit the complex movement of the foot. As a child with a family history of bunions, my mom put me in orthotics, which I hated, perhaps instinctively! Genetics do play a major role in how we are put together! While some feet are more inclined towards orthotics for structural support, I think some doctors would rather make the $500 or so dollars in their pockets versus showing one how to effectively strengthen and mobilize the foot.
