Protect your legs and feet from the inevitable pain and injury that comes with avid walking and running with Enertor's Full-Length Comfort Insoles help guard against injuries like medial-tibia stress syndrome, stress fractures, anterior knee, patellofemoral pain, Achilles tendinopathy and plantar fasciitis. Also suitable for diabetics. Innovative 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. The Ministry of Defence UK mandated Enertor insoles as the only shock-absorption insoles to be used in the British Forces. Imported. Sizes: 8-9, 10-11, 12-13. Color: Black.
