Mizuno's benchmark team spike worn by the athletes of Standford, Georgia Tech, South Carolina, Rice, and Clemson. Weight: 14.0 oz. Features... - 9 Spike Technology Mizuno's patented 9-Spike Technology facilitates superior execution of the three primary baseball movements: running, batting, throwing. This execution is accomplished through the placement of three additional cleats in the forefoot. The placement and the angle of these cleats provide additional lateral stability to the athlete. The 9-Spike configuration provides optimal lateral traction for first step quickness in running and optimal stability to reduce spin out in the batter's box. Additionally, the baseball specific diagonal flex in the forefoot increases pivot traction during the throwing process. - VS-1 VS-1 absorbs shock and enhances cushioning properties by resisting compression-set, thus extending the cushioning life of the shoe. Unique shock absorbing thermoplastics elastomer positioned within the highest initial impact shock areas of the heel and forefoot. Material is constructed from 70% vibration absorption material with the balance being E.V.A. and Isoprene rubber. The combination of all the materials facilitates excellent shock absorption, while also providing an efficient and smooth toe off. VS-1 is lightweight and has a durable memory (returns to original shape after initial impact) ideal for continuous force impact. VS-1 resists compression. The durometer of VS-1 can also be adjusted i.e. Heel wedge is 55 shore C, whereas forefoot is at 40 shore C. In house test results have shown a 20% improvement in shock absorption over E.V.A. - Mizuno Wave Technology Conventional midsoles use flat materials which allow deep penetration at the point of impact. The Mizuno Wave disperses impact forces uniformly over the length and width of the midsole, providing unrivaled cushioning. The Mizuno Wave® is a biomechanically engineered midsole technology that resists overpronation, thus relieving stress on ankle and knee joints. Mizuno's unique Wave® Technology minimizes excessive midsole collapse as the foot lands and rolls medially providing superior motion control. - Proflex Mizuno's proprietary flex construction that is engineered to provide a controlled flex for all three primary baseball movements: running, batting, and throwing. The 9 Spike Classic is the number one Mizuno shoe in college softball. Women add .5 to the mens size. ie: Mizuno mens 8 = Mizuno womens 8.5.
