Experience the WaveSpring® technology of Spira, an innovative footwear company making premium athletic shoes with a patented energy-return system that reduces stress on muscles and provides exceptional cushioning and resiliency. Lightweight stainless steel springs built into the sole unit at heel and forefoot stand up to wear better than compressive foams for an extended “new shoe” feel. The white-berry-and-pewter synthetic-and-mesh “CloudWalker” has breathable uppers, a removable Memory Foam insole, a full-length compression-molded EVA midsole and an UltraGrip full contact rubber outsole for stability and support. Women’s sizes 6–11 and 12 in 4E width. (Sorry, the CloudWalker is not available in 2E width in this color.)
