Superb pair of two original Apollo A7LB pressure boot restraint assemblies, both with ILC Industries tags sewn inside, identifying them as "Part No. A7LB-106078-07" and "Part No. A7LB-106078-08,” both "Serial No. 627, Size 095A." The boots are constructed from a blue nylon fabric designed to hold their form under pressure, with convolutes and restraint cables with ferrules that form the ankle mobility joint. They feature a stiff toe cap and are sewn to beige rubber soles with metal support plates to the arches and to the heels, which are topped with white Beta cloth counter pieces. Encircling the tops are zippers designed to couple the boots to the restraint layer's trouser assembly. In overall fine condition, with some slight wear and scuffing from use.
The A7LB space suit was made of several layers: these boots are part of the blue 'restraint' layer, known as the Torso Limb Suit Assembly (TSLA), which would be sandwiched in between the inflated pressure bladder and the iconic white Integrated Thermal Micrometeoroid Garment (ITMG) outer layer. The TSLA provided structural integrity to the suit by holding the internal suit pressure and contained the mobility elements that allowed the suit to move—thus permitting the astronauts to walk on the moon.
