The sign accompanying the boot. It reads
The lunar boots, donned prior to lunar surface activity, provided thermal and
abrasion protection for the pressure garment assembly boots during lunar
surface operations. The outer layer of a lunar boot, except for the sole, was
fabricated from Chromel-R and the tongue area was made of Teflon-coated Beta
cloth. Ribs projected from the bottom of the silicon rubber sole to increase
thermal insulation qualities, to provide lateral rigidity, and to provide
traction on the lunar surface. The inner layers consisted of two layers of
Kapton followed by five layers of aluminized, perforated Mylar. The Mylar
layers were separated by four layers of nonwoven Dacron followed by an inner
liner of Teflon-coated Beta cloth. Two layers of Nomex felt on the sole
provided additional thermal insulation from the lunar surface.
• This boot was made for Astronaut Charlie Duke and was used in
training for his Apollo 16 Mission.
