All the participants of the Soviet Vostok program used SK-1 space suits, they are the cosmonauts Gagarin, Titov, Nikolaev, Popovich, Bykovsky, Tereshkova. The pressure suit has been designed to prevent Vostok cosmonauts from depressuarization during all stages of flight. Cosmonauts needed the strong boots because they separated from the capsule high in atmosphere and landed with parachute. Vostok capsules landed with their own parachutes. So, the first Soviet cosmonaut boots have incomparable advantages:
This pair of the boots was originally created by NPP "Zvezda" for the first space flights.
The materials used to make the boots are the highest quality (leather etc.).
