26th April 2016 – Usain today announced a new partnership with ENERTOR™. Enertor is a new insole company that helps athletes to perform better and stay injury free. Enertor is the only insole with patented D3O® technology. It’s a smart material that cushions the foot when moved slowly, but on impact locks together to absorb and disperse energy, before instantly returning to its flexible state. This unique characteristic provides enhanced shock absorption — reducing by 44 percent — and proven energy returns of up to 36 percent. See enertor.com for more details.
