Sportswear can easily be the largest individual market, but this includes
purchasing of sportswear to use as leisurewear or casual clothing (e.g. multi-purpose trainers as
casual shoes). It is now impossible to distinguish between the `fashion or function' markets.
Functional items are extremely diverse, with some important niche markets being running shoes,
fleece tops for outdoor pursuits. The sportswear market is driven by strong branding and globalized manufacturing, led by two giant brands which are Nike and Adidas.
