LONDON, Oct 19, 2015:Guess what? Adidas has released a new pair of footwear inspired by Manchester United (MU). But MU fans are not only unhappy, they are horrified. Why? Because these kicks sport the hue synonymous with the Red Devils’ sworn enemy — the Sky Blue (Manchester City). Adidas released the limited edition shoe called the “Stretford”, trying to build on the company’s successful release of a retro Manchester United clothing range earlier this year, news.com.au reports. The name Stretford was inspired by the Stretford End supporters’ section at United’s home ground — Old Trafford. The Stretford features the iconic three stripes, a branding of Adidas’. And those stripes are, unfortunately, sky blue, the colour of Manchester City. The sportswear company justified its design by referencing the blue on the kicks to the club’s jersey in its 4-1 victory over Portuguese side Benfica in the 1968 European Cup final at Wembley Stadium. Supporters, however, pointed out the colour worn in that match was a darker, royal blue as opposed to the light blue evident on the shoe. Angry fans took to social media to express their dismay at Adidas’ decision.
