I have Rheumatoid arthritis and my feet are distorted and painful. I also have callouses or plantar warts on my forefoot.?they are very hard to walk on. I have never found a shoe as good as these. I have bought plenty of high dollar brands, Ecco, Keen. and other tennis shoes as well. These are hands down the best shoe I have worn! They have reduced the size of the warts on my feet! And there is no break in time which for me can cause knee, hip problems. I have 2 pair already and would like another!!
