These 846s are the best shoes I've ever worn. I have plantar fasciitis and hobble around in excruciating pain. These were recommended to me, and though skeptical, I tried them out. They are so comfortable and supportive, they not only don't hurt my feet, they've reduced the pain. I wear them all the time. They are very light and breathable, so I don't have any problems with hot feet. They feel like a cocoon and the pain reduction is so amazing!
