Jet-powered boots that let the wearer hover and fly, used by Spock at Yosemite and in the Enterprise-A's turboshaft in Star Trek V: The Final Frontier.
Levitation boots are footwear fitted with small thrusters that allow the wearer to float in mid-air or climb vertically. They are seen only in the 1989 film Star Trek V: The Final Frontier.
Spock first wears them during shore leave in Yosemite, drifting up beside Kirk as the captain free-climbs El Capitan and questioning the logic of the exercise. When Kirk loses his grip and falls, Spock dives after him and catches him by the ankle just above the ground.
Later, with the Enterprise-A in Sybok's hands, Spock uses the boots again to carry Kirk and McCoy up a turboshaft, firing the booster rockets to escape their pursuers and shooting past deck after deck.
