was there some story behind those shoes?

Under Armour will make official Bryce Clown Question shirts for its contract with Harper
http://sports.yahoo.com/blogs/mlb-big-league-stew/bryce-harper-melky-cabrera-debut-colorful-cleats-star-060642867--mlb.htmlYou had to know Bryce Harper would figure out a way to shine brighter than his fellow All-Stars in Kansas City, even if his play on the field didn't quite measure to his high standards. And that's exactly what he did, debuting a new pair of gold Under Armour's Highlight Spine cleats for all the world to see.
According to the Washington Post's Dan Steinberg, Harper has been wearing
Under Armour cleats (which are designated for greater ankle support) for the past two weeks. For the All-Star game, though, he decided to go with the specially designed gold pair, which Steinberg describes as 'very Bryce Harper.' "Those are great, aren't they?" Harper told Comcast SportsNet's Kelli Johnson. "They're awesome for the camera....They're pretty impressive. They've got that Vegas feel to 'em. I like that gold."
That was Harper before the game. When asked about them after the game, he simply added: "I just told them I want as much gold on there as I can."
