The Mizuno 9-Spike Advanced Erupt 3 Mid Turf Shoes 320508 is a highly competitive and explosive pair of cleats. These cleats are not designed for the weekend warrior but the dedicated ballplayer will fit right in. That is not to say, if you only have time to play on the weekends and need a great pair of cleats that you shouldn t buy them - on the contrary - but it is the dedicated, everyday player that was the inspiration behind these beautiful turf shoes. The foundation of the Mizuno 9-Spike Advanced Erupt 3 Mid Molded Cleats 320508 is outfitted with the proprietary GroundGrip Aggressive Stud Design. While it may be a mouthful, it is certainly worth the extra syllables. You will undoubtedly feel the difference as soon as your foot slides along the full length midsole. The GroundGrip Aggressive Studs help anchor hitters in the box and helps build incredible traction for runners on the base paths. Not to mention, these cleats will absolutely tear up the infield dirt and outfield grass (in a good way). A ProFlex structure makes this a very flexible pair of cleats as well. Flexibility is very obviously a critical part of quick movements. There is unlikely a fast man alive who isn t at least somewhat flexible but the fastest of the fast make flexibility a priority. The ProFlex structure allows the cleats to move the foot without restricting movement. This design helps players make those sharp cuts coming around the bag on the way home. The aforementioned full length midsole comes set up to cradle and surround the foot for increased comfort. The Mizuno 9-Spike Advanced Erupt 3 Mid Molded Cleats 320508 is one of the best looking productive shoes. It may also be the most comfortable pair of cleats ever made.
