Abstract
Footwear including a foot support member and a sole assembly, the sole assembly having a first end and a second end, comprising a plurality of separate insole segments attached to the foot support member for bending the sole assembly, an outsole portion forming the base of the sole assembly, and a plurality of springs engaged between the insole segments and the outsole portion. The springs are arranged in a continuous series across the sole assembly from the first end to the second end, such that the springs exert a constant rebounding force on and across the sole of a user in series throughout a pace cycle.
Claims21
Footwear including a foot support member and a sole assembly, the sole assembly having a first end and a second end, comprising:
- a plurality of separate insole segments attached to the foot support member to facilitate bending of the sole assembly;
- an outsole portion comprising the base of the sole assembly;
- and
- a plurality of springs engaged in a continuous series between the insole segments and the outsole portion from the first end to the second end to cause the springs to exert a constant rebounding force on and across the sole of a user throughout a pace cycle.
A sole assembly of a shoe, the sole assembly comprising:
- more than one insole segment rotatably attached to an adjacent insole segment;
- a spring device disposed between each adjacent insole segment to bias each insole segment in a parallel position relative to the adjacent insole segment;
- an outsole portion with a first end and a second end, the outsole portion comprising the base of the sole assembly;
- and
- a plurality of springs engaged in a continuous series between the insole segments and the outsole portion from the first end to the second end to cause the springs to exert a constant rebounding force on and across the sole of a user throughout a pace cycle;
- wherein springs proximate to the first end of the outsole portion are axially tilted backward relative to a central axis of springs disposed midway between the first end and the second end and springs proximate to the second end of the outsole portion are axially tilted forward relative to a central axis of springs disposed midway between the first end and the second end.
