About the original
Castelli cycling socks are knit in Italy from moisture-wicking synthetic fibers with anatomically shaped left and right construction and a mid-calf cuff, the height regulated by the UCI as the maximum allowed in professional road racing. Castelli was founded in Milan in 1876 and is one of the oldest continuously operating cycling apparel brands in the world. The company has supplied jerseys to more Tour de France winners than any other manufacturer, from Eddy Merckx's Molteni team onward. The SS25 collab is a three-way drop with Nickelodeon, printing SpongeBob SquarePants and Patrick graphics across the sock body alongside Castelli's scorpion logo and Supreme branding.
About Castelli
Castelli is an Italian cycling apparel manufacturer tracing its origins to an 1876 Milan tailoring shop run by Vittore Gianni, which clothed football clubs including Milan and Juventus and cyclists including Alfredo Binda. Armando Castelli joined in 1935 and bought the business, supplying Gino Bartali, Fausto Coppi, and Jacques Anquetil. In 1974 his son Maurizio Castelli founded the current company under the scorpion logo, and in 1977 introduced Lycra to cycling shorts, a first in the sport. Castelli now outfits UCI WorldTour teams including Soudal Quick-Step and produces the Gabba jersey line. Supreme has released co-branded Castelli cycling apparel.
