Mike Ashley is the king of stack um high and sell um cheap. This is from his wiki page:
Ashley has made his money by buying brands. The first major brand he bought was Donnay. In February 2003 Ashley bought the Dunlop Slazenger brand for £40 million, followed up by acquiring outdoor gear manufacturer Karrimor in March 2003,[10] Kangol for £10 million,[11] boxing brand Lonsdale, most of these brands were bought from distressed sellers. After considering a takeover,[12] Ashley took a £9 million stake and signed a long-term deal with Umbro.[13]
He has mastered the model of, buy an established sportswear co, close it down and apply the branding to far eastern tat. I would stay away from all of it although he might still be selling some decent Karrimor boots etc by just continuing the production of the old lines. I still have gore tex ksb boots that are c10 years old and are going strong but I won’t be buying more.
