During his Year in Space, Scott Kelly said that the weirdest thing to happen to him was the formation of calluses on the tops of his big toes as a result of using the foot rails to move around. The FootShield is the solution to this problem. It fits on the astronaut’s left foot and covers their big toe, providing a layer of protection from the foot rail. The FootShield can be worn by astronauts with a variety of foot sizes, as the pieces can be adjusted to fit each individual. With the FootShield, Astronauts on the ISS will never have to deal with calluses on the tops of their big toes ever again.
