Yes, you can continue to do anything you want to.....once you
dial in the ortho/shoe combo. The shoes that worked best for
my wife were Naturalizer walking or Redwing womens athletic
workshoes. Good stout womens shoes both. It takes that kind
of aggressive support to allow the foot to heal. You'll find
that with the proper combo you won't want to ,nor should you,
wear any other shoes until you are healed. My wife tried heels
just once for about 5 min till off they came in pain while
she was healing.
As to what causes this injury.......
From what we learned it's a combination of cheap/bad shoes &
overextending while in them. It would be better to overextend
barefoot than in bad shoes. Your foot will protect itself.
So get fitted for otho inserts and shoes as soon as you can
as delay may make the injury much harder to heal.
