Style#: BQ3177-006 Designed specifically for Lebron, Nike Basketball’s largest heel Max Air unit to date absorbs more force than previous designs. Visible, maximum-volume Zoom Air units under the ball of the foot provide quick, continuous responsiveness to generate fast-paced action. Wide collar with traditional tongue makes putting on and taking off easy while providing a comfortable, locked-in feel. Soft foam pod directly under the Max Air unit adds cushioning in the heel. Stabilizing plastic clip wraps around heel to lock you in.
