After signing with Under Armour in December, tennis star Andy Murray was supposed to be dressed head-to-toe by the Baltimore sports apparel brand - with one caveat that became conspicuous this week.
The three parallel, Adidas stripes are unavoidably evident on the British star's tennis shoes this week in the opening round of the U.S. Open.
Adidas couldn't resist having some fun – at Under Armour's expense – at the sight of Murray so publicly wearing an Adidas product. Under Armour surpassed Adidas last year to become the second-biggest sports brand in the United States
Murray's footwear may have surprised some observers since he became Under Armour's best known tennis player after signing in December. Murray, who advanced to this week's second round, is the 2012 US Open Champion and 2013 Wimbledon Champion.
There is an explanation for Murray's shoe choice. Experts say the typical footwear development process can take 18 months. Under Armour has developed custom footwear for Murray to wear on clay and grass, but not yet for the hardcourt surfaces of the U.S. Open.
Those shoes are being created now.
In the meantime, Murray – who previously had partnered with Adidas – won't quite represent Under Armour from head to toe.
