These boots were worn by Scott Carpenter during training sessions prior to his Mercury mission in May 1962.
The Mercury boots were designed to be worn separately, over the spacesuit bladder, and were constructed of lightweight, nylon-fabric with tennis-shoe-type soles. The upper surface was of nylon, covered with the same aluminized coating as the spacesuit, with front closing zipper and adjustment lacings on each side. The soles were constructed of rubber.
The NASA - Manned Spacecraft Center transferred the boot to the National Air and Space Museum in 1972.
