Guard your legs and feet from the inevitable pain and injury that comes with running, hiking and playing sports with Enertor's Full-Length Performance Insole. They improve muscle function, reduce pain and fatigue, improve posture and increase stability of the foot. Innovative, water-resistant D30® material cushions your feet while you're moving slowly but locks together on impact to absorb and disperse energy, and then it returns to its flexible state, so you can keep trucking along in comfort. This unique material has been proven by numerous SATRA tests to provide 61% more shock absorption, 44% shock reduction and 36% energy return, which helps reduce the chances of lower-limb injuries. Plus, the material delivers superior durability and lasting performance while remaining ultrathin. Also suitable for diabetics. Imported. Whole sizes: 9-13 medium width. Color: Black.
