Since 1998, Enertor has been used and trusted by athletes, the army and many more professionals across the world. The brand is even used and endorsed by Usain Bolt, making it the only insole range that the champion uses. Enertor insoles are designed with innovative D30 material. Although naturally flexible, the molecules lock together on impact to absorb shock, then return to its flexible state almost instantly. This helps prevent conditions like plantar fasciitis and midfoot discomfort.
