These boots are made for walking! The new casual group from Think! leaves nothing to be desired when it comes to walking pleasure. The platform sole cushions and insulates and makes the heel shoes extremely comfortable. For very slim calves, the tight-fitting boot (83198) is the right choice. The Obajo ankle boots and boots have a removable footbed, i.e. the insoles can be replaced with orthopaedic or later with new Obajo insoles.
