About Nike

Nike is an American athletic footwear and apparel brand founded in 1964 by Phil Knight and Bill Bowerman, originally as Blue Ribbon Sports, before adopting the Nike name in 1971. The brand is headquartered in Beaverton, Oregon. Nike designs performance and lifestyle footwear and apparel across running, basketball, football, training, tennis, golf, skateboarding, and sportswear categories, for men, women, and children. The brand's footwear lines include the Air Jordan, Air Max, Pegasus, Vaporfly, Dunk, Blazer, and many other iconic silhouettes that span performance and lifestyle markets. Nike operates extensive UK retail through standalone stores (including Nike Town in London), partner retailers, and nike.com. The brand's combination of performance technology and cultural relevance has driven decades of leadership in global athletic apparel. Nike deals typically appear in a continuous Outlet section, NikePlus member promotions, end-of-season clearance, and major sale events.

Nike sizing guide

Nike footwear generally runs true to UK size, though some basketball and training silhouettes (including selected Air Jordan models) can fit slightly snug — half-sizing up is sometimes recommended for these. Nike apparel runs true to UK standard for tops, with some styles offered in slim or relaxed fits noted on the product page.

When does Nike go on sale?

Nike maintains a continuous Outlet section with year-round markdowns, alongside seasonal end-of-line sales typically in late August (end of summer), December–January (end of year), and Black Friday. NikePlus members often receive earlier access and additional discount codes.
