Pain free walking all day has been the result of wearing these Hedgehog GTX's purchased after highly trained staff member recommended them on fitting. I can't praise the staff or the shoes too hightly. I've since bought another pair. Anyone wishing for total comfort should try these sturdy, light shoes. I wore them for a whole month in the Australian outback and recently on a walking holiday in the foothills of the Himalayas. There's no need for additional inners as North Face have thought of everything.
