Definitions

  • the present invention relates to a running shoe, and more particularly, the present invention relates to a shoe for both normal running and controlling pronation.
  • Modem running shoes are not just designed for protection and comfort but to improve miming performance.
  • the midsole must perform with a mix of distinctive characteristics i.e., cushion, support, and energy return.
  • the cushioning of the midsole softens the impacts received at every stride and so the heel area of the shoe generally has thicker cushioning.
  • the midsole can behave as a compressed spring that returns a portion of energy helping the athlete in the toe-off phase.
  • the shoe has to be soft, firm, and elastic which are in contrast to each other.
  • the midsole should have good dampening characteristics.
  • a desire is there a shoe or midsole that is economical to manufacture and can provide for both normal mnning and controlling overpronation.
  • a principal object of the present invention is therefore directed to a midsole for sports shoes that is suitable for normal foot and overpronating foot.
  • the midsole can be made of a single material.
