Amazing light blue Apollo-era EVA molded latex boot sole, measuring approximately 13.75 x 3.5 x 6.25, with wide horizontal tread lines each .25″ deep, .75″ wide, and ranging in length from 3.5″ to 5″, with overall thickness of latex roughly .25″. In fine condition. From the personal collection of Charlie Dry, a former Apollo test astronaut and research engineer and senior scientific analyst at NASA. Designed specifically for extravehicular activity, this is an ideal example of the sole that first walked across the lunar surface.
