This signature model of star athlete Jennie Finch is designed with superior support, durability, cushioning, and protection for the elite fastpitch player. Lightweight upper is made of DSL − Dynamic Synthesized Leather™, which provides a comfortable, yet protective fit. Proflex™ is the proprietary flex construction that is engineered to provide a controlled flex for all three primary baseball movements: running, batting, and throwing. Cushioned textile insole for comfort and shock absorption. Mizuno Wave® disperses impact forces uniformly over the length and width of the midsole, providing unrivaled cushioning. Biomechanically-engineered midsole resists overpronation, thus relieving stress on ankle and knee joints. 9-Spike™ Technology for maximum lateral stability and traction, which is accomplished by adding three additional cleats to the forefoot. PVC free. Weight: 9 oz Product measurements were taken using size 6. Please note that measurements may vary by size.
