A painful condition affecting the bottom of the feet of people who have suffered through winter with shoes on for six months and then begin walking on their driveway, street or other rough surface. Initially excruciating, it remains annoyingly uncomfortable for 1 to 2 weeks until the skin thickens, but is not considered life threatening.
Man, my springfoot is so bad I had to wear flip-flops down the driveway to get the mail!
