A The terms and conditions of the UK Adidas webstore (adidas.co.uk) states there are three conditions where damaged or defective products are not refunded:
Adidas state that it is extremely rare for any of their products to be damaged or defective; however it does happen. If your product is damaged or defective - and it is not due to one of the reasons listed above - then Adidas will issue a full refund. When you return a damaged or defective product to Adidas they have a 'Quality Assurance Department' that will examine your returned product before issuing a refund. The Adidas subsidiary company that manages the online orders for Adidas is different to the Adidas subsidiary companies that manage the 'real world' bricks and mortar Adidas stores; this is the reason Adidas will not offer a refund on Adidas products bought from other Adidas sources; and of course third party sources.
