Under Armour Yard Trainer - Men'sWhen you're training for victory, do it in the more aggressive Yard Trainer. It uses a combination of breathable, perforated nubuck and structured synthetic in the upper to give a comfortable, snug fit. That's backed up by the abrasion-resistant toe piece that protects during medial toe drag. Inside, a 4D Foam® insole custom forms to your foot for optimal shock absorption. It gives great rebound while preventing internal slipping for increased lateral stability. The outsole features an ArmourLastic® heel for shock absorption. It gets a boost from full-length ArmourBound® cushioning that gives you the optimal amount of energy return with every step. The total-contact, rubber outsole is non-marking, making it great for indoor as well as outdoor training. Wt. 10.8 oz.
