History and evolution

Footwear technology has progressed in waves, each driven by a blend of material science breakthroughs, manufacturing capabilities, and user demands. Early boots and sandals relied on locally available hides and fibers, with comfort and protection as the primary goals. The shift to mass production in the 19th and early 20th centuries brought vulcanized rubber and standardized lasts that made athletic and work footwear more affordable and consistent. The invention of vulcanization by Charles Goodyear and subsequent polymer breakthroughs laid the groundwork for modern soles and midsoles vulcanization rubber.

The mid-20th century saw a surge of interest in running and sport footwear, with foams like ethylene-vinyl acetate (EVA) and polyurethane becoming standard in midsoles for shock attenuation and energy return. The rise of performance athletics created demand for lighter, more responsive shoes, and brands began to experiment with different outsole geometries, uppers, and last shapes. The late 20th and early 21st centuries brought a wave of innovations—engineered knit uppers for better fit and breathability, data-informed fit concepts, and the first real popularization of carbon-fiber components in performance footwear. The use of carbon-fiber plates in racing shoes, popularized in the 2010s, sparked widespread attention and debate about performance enhancement in sport. carbon fiber knit uppers running performance footwear.

Key moments and terms in this arc include the transition from leather-and-rubber to synthetic and hybrid constructions, the adoption of cushioning technologies that balance weight and impact protection, and the rise of digital tools for design and testing.
