Motion Efficiency System ; During activity, your foot goes through four motions braking, supporting, flexing and propelling and follows a curved center of pressure path. Timberland’s engineers have designed B.S.F.P. lugs aligned along this path to deliver improved traction and longer wearing performance. Brake lugs on the heel are orientated with leading edges toward the front of the shoe to help brake the foot and increase traction. Support lugs under the arch of the foot increase the stiffness of the outsole between the heel and ball of the foot for stability and support. Flex primary flex grooves are located behind the ball of the foot with secondary flex grooves in the toe area to respond to your foot’s natural motion. Propel lugs in the forefoot are orientated with the leading edges toward the rear of the shoe to help you push off when accelerating and/or climbing.
