Setting the performance standard for Spira's running footwear line, the Genesis II combines Spira's engineered cushioning technology and proven stability features in one shoe. The unique WaveSpring™ technology, found in both the heel and the forefoot, provides unsurpassed cushioning and energy return while providing a stable platform for runners who have stability needs. The WaveSpring™ does not breakdown and maintains "like new" cushioning performance throughout the life of the shoe, while reducing impact shock, stress and fatigue. The midsole design incorporates a special flex plate for increased flexibility and a firmer density medial post and external shank for support, which works with the highly supportive upper design to resist over pronation dynamics.
