X-ray of an extravehicular (EV) overshoe that was designed to be worn over the Apollo spacesuit boots while an astronaut was walking on the Moon. The International Latex Corporation made the boots for astronaut James B. Irwin for training purposes only. The EV boots were worn over the boots that were integrated into the spacesuit and which included the pressure bladder and thermal coverings. The boots were made with a silicone sole, woven stainless steel upper (Chromel-R), and included additional layers of thermal protection and beta felt in the soles as protection against extreme temperatures and sharp rocks on the lunar surface.
