This past weekend, students at Washington DC’s Gonzaga High School had the opportunity to attend the Under Armour Grind Session. The Grind Session is essentially a travelling skills clinic that focuses on training. The the latest session, the students were given a special colorway of the Under Armour Spine Bionic. Sporting a heavy dose of snorkel blue, the model is accented with poison green and black. A Micro G sock liner provides a smooth responsive ride, while a mesh upper keeps the shoe breathable.
