The New Spira® Scorpius II stability running shoe is the latest version of this proven model. It provides support for the moderate to extreme pronator by incorporating a wide heel platform and a high density medial post to assist in proper alignment of the foot throughout the gait cycle. Lightweight WaveSprings in the forefoot and heel provides superior cushioning and comfort and helps to protect feet and joints against impact, stress and fatigue. The midsole uses a rigid TPU shank, offering midfoot support and stability. The redesigned upper incorporating the new 3D molded SpiraCage instep lock technology provides a much better fit and feel than the first generation. The foot-bed may be removed to accommodate orthotics or over the counter inserts.
