Pair of triangular metal shoes cleats used by Lousma during the SL-3 Skylab mission, measuring approximately 3 x 3, each signed and flight-certified on the bottom in black felt tip, “Flown Skylab II, Jack Lousma.” The blue cleat, designed for the left foot, is labeled “P/N: BW-2091-003, S/N: 025,” and the red cleat, designed for the right foot, is labeled “P/N: BW-2091-004, S/N: 025.” In overall fine condition. Accompanied by a signed letter of provenance from Lousma, in part: “I hereby certify that the pair of accompanying metal Triangle Shoe Cleats…are the pair that were attached to my shoes and used every day by me on Skylab II (SL-3), July 28–September 25, 1973. The triangles fit the grid work of the floor, ceiling, and work station platforms on the interior of the Skylab Space Station. The triangle shoe cleats were inserted into the triangle grid and the heels were rotated outboard to lock the cleats to the grid for body stabilization. Rotating heels inboard freed the cleats from the grid. These cleats are from my personal collection and have been in my possession since the mission.” Also includes an official color 10 x 8 NASA lithograph signed in black felt tip by Lousma, “Jack Lousma, Pilot, Skylab II,” who also draws arrows to the cleats which can be seen on his feet, labeling them, “Red & Blue Triangle Cleats.” A superb flown and certified pair of essential items used every day, further enhanced by photographic evidence. Pre-certified Zarelli Space Authentication.
