Designed to reduce heel pain!  Usain Bolt demands the best possible performance and Enertor heel cups deliver.  Their D3O patented smart material cushions the foot when moving slowly, but locks together on impact to absorb and disperse energy, before instantly returning to its flexible state.

  • Contoured cushioning thanks to a moulded heel cup
  • Reduces shock by up to 44%
  • Flexible and light weight to be suitable for all footwear
  • Worn and endorsed by Usain Bolt
