Tuuk LS Pulse Premium Grade Steel Runner Retail price: 16,000 yen Designed with a high-gloss mirror finish, it provides excellent glide for increased speed. Also, the increased height improves the angle of attack. - Power Profile - Four zones, called the Quad Profile, are uniquely designed to enhance performance. 1. The zone near the toe maximizes acceleration. 2. The transition zone shifts the stride from rapid acceleration to a longer stride, and the center of gravity shifts slightly backward from the acceleration stride. 3. The speed zone maximizes blade-to-ice contact for efficient power transmission and straight-line speed. 4. The stability zone towards the heel provides balance when pivoting and shifting between edges when absorbing. Bauer Runner 221
