I've been wearing Z-Coil shoes for 7 years. When I walked 3 blocks in every other shoe I tried, the pain made me stick my feet out for hours. For the FIRST time in a day I walked the Z-Coil 2 miles on a 12 block per mile path and NEVER had to raise my legs. When transitioning to a new style, it took me a while to find the right size and the right pair for my odd height. Feet, online. Easier in store but help was respectful and very good online.
