Selling soles Sports shoes were up and running by the mid-19th century, after American Charles Goodyear invented vulcanized rubber. Billed as a flexible alternative to leather, the rubber-soled sports shoe was adopted by the US Rubber Company in 1892, which established the Keds business in 1917 to make and market the shoes.

Soon, many companies were producing shoes that combined comfort and style. Lightweight canvas uppers allowed air to circulate, while laces were loosened or tightened as required. The shoes were nicknamed “sneakers” because their vulcanized rubber soles let the wearer sneak around without being heard.

Laces are fed through metal eyelets (holes).

Staying ahead of the game In the 1930s, shoe companies began tailoring their products to sports.

Today’s high-tech sneakers include automatically adjusting cushioning systems that adapt to the individual wearer and specific surface to ensure peak performance.
