Specifications

• 5-Spring Propulsion System: Feel instant energy return with every step—ideal for work boot insoles for men and women! 5 medical-grade steel springs absorb shock during heel strike and convert it into forward momentum, boosting running pace by 2 %–5 % in independent third-party tests
• Triple-Layer Impact Defense: a PU base cushions your arch for plantar fasciitis relief, Premium PORON material in the forefoot pad shields the balls of your feet, and a rigid TPU heel cup locks the springs in place—lasting twice as long as foam or gel insoles
• Orthopedic-Grade Arch Support: a TPU bridge redistributes 66 % of plantar pressure—compared with only 40 % for plastic arches—relieving pain from plantar fasciitis and flat feet. That’s why these orthotic insoles come podiatrist-recommended for overpronation
• Firm Arch Support + Spring Shock Absorption: 8-hour nurse & construction tests show 80% heel-pain reduction. These arch support inserts for men and women use built-in springs—unlike collapsing memory foam—to shield knees & back from impact and relieve plantar fasciitis, high arches, flat feet, metatarsalgia & heel pain
• 360° Adaptive Design: These dynamic spring insoles help relieve plantar fasciitis while providing high arch support for women and men. The trim-to-fit shape ensures a custom fit, while the moisture-wicking top fabric combats odor. 90-day “Run Test” guarantee
