Perhaps you are talking about a minor avulsion fracture of the styloid process of the base of the 5th metatarsal. That is sometimes treated with as little as firm taping and a stiff-soled or surgical shoe, but walking casts or walking boots are probably more commonly employed. The determination of what is best for any individual case should be left to the attending doctor who should, as in every case, be selected and vetted with care.
