Pinnacle Insoles offer the perfect blend of foot control, spring and life-long cushioning. The prescription-like supports are sealed in two layers of foam. The inner foam Hypurcel maintains its density and cushioning properties and a soft EVA outer foam. A permanent antibacterial and anti-fungal top fabric combats foot odor and helps keep feet drier. Pinnacle Insoles reduce excessive inward rolling motion of the foot to virtually eliminate pain or strain in the heel and arch, and even in the ankles, knees and lower back.
