The Timberland Chocorua Trail is a lightweight trekking and outdoor shoe. B.S.F.P. During activity, your foot goes through four movements: braking, supporting, bending, and propulsion, following a curved motion of the pressure point. Timberland has developed the B.S.F.P. system, which ensures better grip and longer wear by aligning with the pressure point. For the braking function, the lugs on the heel are angled forward to facilitate braking. For the supporting function, lugs are raised under the arch for increased stiffness, stability, and support of the foot. For the bending function, the flexible lugs respond to the natural movement of the foot. Lastly, for the propulsion function, the lugs at the forefoot are angled backward to aid in push-off.
