Abstract
The present invention addresses an elastomeric sole having a sidewall with a height less that 0.625 inch, forming a cavity and a horizontally disposed rim extending from the top surface of the sidewall. The sole includes at least two upstanding regions extending upwardly from the cavity lower surface, each region formed from elastomer and having a different effective modulus of elasticity. The invention also includes the combination of an elastomeric sole and an upper and a method for sewing an elastomeric sole to an upper by means of a converted sewing machine.
Claims14
An elastomeric sole, comprising:
- (a) a sidewall having a top surface, a bottom surface, and a height extending therebetween, said height being less than about 0.625 inch;
- (b) a cavity lower surface which with said sidewall forms a cavity;
- (c) a horizontally disposed rim extending outwardly from said sidewall;
- and
- (d) at least two upstanding regions extending upwardly from said cavity lower surface, each region formed from elastomer and having a different effective modulus of elasticity, and each said upstanding region including a plurality of tubular members formed from upstanding tubular walls, each tubular member extending vertically upwardly from said cavity lower surface, said tubular member walls having a thickness corresponding to a said effective modulus of elasticity.
A combination of an elastomeric sole and an upper, comprising:
- an elastomeric sole comprising:
- (a) a sidewall having a top surface, a bottom surface, and a height extending therebetween, said height being less than about 0.625 inch;
- (b) a cavity lower surface which with said sidewall forms a cavity;
- (c) a horizontally disposed rim extending outwardly from said sidewall;
- and
- (d) at least two upstanding regions extending upwardly from said cavity lower surface, each region formed from elastomer and having a different effective modulus of elasticity, each said region including a plurality of tubular members each extending vertically upwardly from said cavity lower surface and having a thickness corresponding to a said effective modulus of elasticity;
- and
- an upper comprising:
- (d) a continuous connector ledge extending about its lower surface, said continuous connector ledge being sewn to said elastomeric sole rim.
