I have just heard that a clothing company, presumably adidas has complained about Laura Muir wearing the nike 4% spikes in her british mile record in birmingham. Personally I think she is a stuck up bit** as she is always complaing about her competition and the nike oregon project. I think nike is doing great advancing shoe technology and helping athletes realise their potential and making racing more excity but they should not be so secretive about their prototypes and they should make them available to consumers.
