Vintage U.S. Pro Keds Basketball Shoe Print Ad Featuring PowerLift Technology
The advertisement for U.S. Pro Keds shoes highlights the basketball shoe's successful launch across the United States, particularly emphasizing its widespread acceptance in over 1,100 colleges and high schools. Featured prominently is the U.S. Royal "PowerLift," a patented technology designed to keep the foot secure within the shoe, prevent slipping, and enhance athletic performance. The ad states that this shoe was a significant player in the 1957 basketball season, marketed as essential for athletes seeking improved speed and stability on the court. The design is complemented by features such as a molded suction sole, preventing foot movement that could lead to discomfort and blisters. U.S. Rubber, located at Rockefeller Center in New York, positions the Pro Keds as the "Shoes of Champions," appealing directly to basketball players and teams during a time when NCAA basketball was gaining prominence.
