The fiercest on the field now get speed with their support. The Under Armour Spine Fierce Mid D uses a newly innovated CLUTCHFIT™ upper. It expands with the foot, but doesn't get thin or vulnerable. It protects the foot, doesn't rip, and stands up to everything you throw at it. Your foot is locked into it with a power strap that keeps you centered and stable over the molded 4D Foam® footbed. Players know the material for its extreme comfort and custom-molded feel. It's especially important for the tall and heavy players that need cleat pressure drastically reduced. The outsole is a lightweight TPU plate with seven-stud detachable configuration. It gets extra stability from UA's Spine technology. It uses Pebax® to reduce the overall weight of the outsole, but promote strength for the entire length of the foot. Wt. 14.3 oz.
