Abstract
The present invention relates to a shoe sole, in particular for a sports shoe, where the sole includes a cartridge cushioning system that includes a load distribution plate arranged in a heel region of the shoe sole, at least one cushioning element for determining the cushioning properties of the shoe sole during the first ground contact with the heel, and at least one guidance element to guide the foot into a neutral position after the first ground contact.
Claims20
A sole for an article of footwear, the sole comprising:
- a load distribution plate disposed in a heel region of the sole;
- a cushioning element disposed proximate the load distribution plate, the cushioning element configured and located to determine a cushioning property of the sole during a first ground contact with the heel region;
- and
- a guidance element disposed proximate the load distribution plate, the guidance element configured and located to bring a wearer's foot into a neutral position after the first ground contact.
An article of footwear comprising an upper and a sole, the sole comprising:
- a load distribution plate disposed in a heel region of the sole;
- a cushioning element disposed proximate the load distribution plate, the cushioning element configured and located to determine a cushioning property of the sole during a first ground contact with the heel region;
- and
- a guidance element disposed proximate the load distribution plate, the guidance element configured and located to bring a wearer's foot into a neutral position after the first ground contact.
An article of footwear comprising an upper and a sole, the sole comprising:
- a load distribution plate disposed in a heel region of the sole;
- a cushioning element disposed proximate the load distribution plate, the cushioning element generally located in a lateral rear quadrant of the heel region and configured to determine a cushioning property of the sole during a first ground contact with the heel region;
- a first guidance element disposed proximate the load distribution plate, the first guidance element generally located in a lateral forward quadrant of the heel region and configured to bring a wearer's foot into a neutral position after the first ground contact;
- a second guidance element disposed proximate the load distribution plate, the second guidance element generally located in a medial rear quadrant of the heel region and configured to bring the wearer's foot into the neutral position after the first ground contact;
- and
- a stability element disposed proximate the load distribution plate, the stability element generally located in a medial forward quadrant of the heel region and configured to avoid excessive pronation during transition to a rolling-off phase of a step cycle.
