The choice of material directly impacts the durability and perceived value of the footwear. For mass-market athletic shoes, cellulose acetate (plastic) is the standard due to its low cost and high-speed application via heat-shrinking machines. For premium sneakers or luxury dress shoes, metal aglets (made of brass, zinc alloy, or stainless steel) are preferred. Metal options offer superior aesthetic appeal and can be finished with electroplating (gold, gunmetal, rose gold) or laser-engraved logos to enhance brand identity.
