PRODUCTION METHOD OF GLUELESS PASTED INTEGRALLY MODELING SHOE SOLE
20170297287 · 2017-10-19 ·

A production method of glueless pasted integrally modeling sole comprising the following steps: taking a rubber outsole compound in a mold to perform partial vulcanization; taking a midsole compound in the mold to simultaneously perform pressurizing and heating together with the rubber outsole compound that has been partially vulcanized to simultaneously generate more vulcanization of the rubber outsole compound and foaming reaction of the midsole compound and occurring adhesion; and completing glueless adhering and pasting for the rubber outsole and the foaming midsole after the mold is cooled down so as to obtain a sole finished product. Accordingly, it can greatly reduce the procedure of forming soles, decrease labor force at great quantity and energy use, and reduce the proportion of producing waste and also achieves the efficacies of reducing costs and energy saving and carbon reduction at the same time.

Basketball insole

An insole which provides cushioning and support to a user's foot subjected to a high magnitude of ground reaction forces (GRF) encountered in playing court sports, such as basketball, is herein disclosed. The insole comprises a base having a bottom side which defines recesses adapted to receive pads having particular properties. The location and materials of the various pads and pods work together to provide ground reaction force modulation to the user's foot which is highly desirable for users engaged in basketball and similar activities.

Footwear strobel with bladder and lasting component and method of manufacturing

An article of footwear includes a strobel that has a polymeric bladder defining an interior cavity and configured to retain a fluid in the interior cavity. The polymeric bladder has a peripheral flange extending around at least a portion of a perimeter of the interior cavity. A tensile component is disposed in the interior cavity and is secured to opposing inner surfaces of the polymeric bladder. The peripheral flange defines a groove extending along the peripheral flange. The strobel also includes a lasting component configured to extend along the peripheral flange around the at least a portion of the perimeter of the interior cavity. The lasting component is secured to the peripheral flange. A method of manufacturing footwear that includes the strobel is disclosed.

Laminate, shoe sole, and shoe

A laminate of the present invention includes a first member which contains a thermoplastic polymer and through which laser light is transmitted and a second member which contains a thermoplastic polymer and absorbs laser light, wherein the first member is directly bonded to the second member, and A represented by the formula 1: A=−9×D+Wa−45 is more than zero. D represents a distance between a Hansen solubility parameter of the thermoplastic polymer of the first member and a Hansen solubility parameter of the thermoplastic polymer of the second member, and Wa represents work of adhesion calculated from each surface free energy of the first member and the second member. Such a first member and a second member are firmly bonded to each other without using a bonding sheet.
