About Adidas
Adidas is a German sportswear brand founded in 1949 by Adolf Dassler in Herzogenaurach, Bavaria. The brand designs performance and lifestyle apparel and footwear across running, football, training, basketball, tennis, originals/streetwear, and outdoor categories. Adidas serves men, women, and children and operates extensively across the UK through both adidas.co.uk and physical retail. The brand's three-stripe trefoil identity is among the most recognised in global sportswear. Adidas product lines split between performance categories (Climacool, Boost, Adizero) and lifestyle/Originals collections, which include heritage silhouettes like the Samba, Gazelle, Stan Smith, and Superstar that have driven major resurgences in recent fashion cycles. Adidas deals typically appear across the Outlet section of adidas.co.uk year-round, alongside seasonal promotions, member-exclusive discounts via the adiClub loyalty programme, and end-of-line clearance.
