The sign accompanying the boot. It reads
Overshoe, Lunar- Left, Training
This overshoe went over the regular boot
area on the space suit version used on the moon, called the A7LB space suit. The
shoe provided extra protection from rips, tears, and dust to the basic space
suit. These overshoes left the distinctive
footprints which are still on the moon to this day.

Smithsonian Institution, Washington D.C.
By virtue of the retaining strap assembly
being anchored on the right and snapping on the left, it seemed to me that this
was actually a right boot.
I emailed the museum's curator, who confirmed that records from the Smithsonian
indicated that it was a right boot.
