With the 2013 MLB Home Run Derby taking place tonight in NY, Under Armour has laced contestant Bryce Harper with a special edition of their Spine Highlight ST cleat. The innovative footwear boats the brand's Micro G cushioning in the midsole, as the cleat is recognized as one of the lightest and most supportive around. The bright colorway is a nod to the home team Mets as well as the pair matching the unis that the participants will be donning tonight during the festivities. Expect the UA Spine Highlight ST to become available during the month of October, but first get a look at them in action tonight, courtesy of Bryce Harper.
