Spira Genesis II SRG301 – Men’s Overviews
bThe 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. The Genesis II contains WaveSpring technology in both the heel and the forefoot to provide a remarkable combination of cushioning and energy return with a high density medial post for stability./b
