Adidas is a German sportswear giant founded in 1949 by Adolf "Adi" Dassler. The brand is one of the largest athletic shoe manufacturers worldwide, producing footwear for running, football, basketball, lifestyle, and more. Adidas is known for its three-stripe trademark and innovative technologies like Boost, 4DFWD, and Lightstrike cushioning.

Adidas sizing varies by model category. Running shoes (Ultraboost, Supernova) typically run true to size. Lifestyle models (Stan Smith, Superstar) fit true to size but can feel narrow. Football boots are designed for a snug, locked-in feel. The Yeezy line (produced with Adidas) runs noticeably small.

For most Adidas sneakers, order your regular size. If you have wide feet, consider half a size up in lifestyle models like the Stan Smith or Gazelle. Running shoes like the Ultraboost fit true with a stretchy Primeknit upper. For Samba and Spezial, stay true to size as the leather gives slightly.
