Saucony's ProGrid Jazz 12 is an entry-level neutral running shoe that uses Saucony's ProGrid sole that reduces and dissipates the force of impact throughout the foot and make for a continuous transition during contact with the ground. The midsole is lightweight and provides cushioning when running, and the insole features anti-microbial and anti-odor properties that are supposed to maintain the shoe's condition. It is made of lightweight material and weighs just over 11 ounces. Both the midsole and sole are supposed to be long-lasting.
