CN-116249461-B - Shoe assemblies with dual insole boards and related methods

Abstract

A shoe assembly has an insole assembly with a heel insole board and a dual insole board above a midsole having a heel portion more rigid than a forefoot portion. The bottom edge flange of the upper wraps around the sides of the heel portion and the arch portion of the dual-purpose insole board behind the attachment transition region. At least a portion of the flange is adhered between the dual mode insole board and the heel insole board. The flange of the upper is positioned adjacent to the lateral sides of the forefoot portion and the arch portion of the dual mode insole board forward of the attachment transition area without wrapping under the dual mode insole board. The flange of the upper is sewn to the top or edge of the forefoot and arch portions of the dual mode insole board forward of the attachment transfer area.

Description

Shoe assemblies with dual insole boards and related methods Cross reference to related applications This patent application claims the benefit and priority of U.S. provisional patent application No. 63/074,408 entitled "shoe Assembly with double (bifit) insole board and related method" filed on even 3/9/2020, which is incorporated herein by reference in its entirety. Technical Field The present disclosure relates generally to shoe assemblies having stiffness transitioning along a footbed (bootbed), and more particularly, to shoe assemblies having sole assemblies with variable stiffness insole assemblies. Background Articles of footwear have been designed for a wide variety of athletic activities, including walking, running, hiking, long-distance trekking, hunting, knapsack travel, and indoor and outdoor activities. For example, hiking and work boots are often designed to provide proper comfort and support for the wearer to hike or walk on uneven or rough terrain. However, conventional hiking boots or work boots may be relatively heavy. Each time the wearer takes a step, such as walking or hiking, the wearer must lift the weight of the boot. The additional weight may fatigue the wearer's legs over hundreds or thousands of steps. It is therefore highly desirable to minimize the weight of the shoe without unduly compromising the stability and support of the shoe. Shoes, such as boots, are often designed to follow a typical wearer gait cycle. A typical gait cycle includes several phases, including heel strike, ball strike, heel off, and toe off. During heel strike, the boot initially lands approximately on the rear medial portion of the boot heel region. As the gait cycle proceeds from heel to sole, a load is applied along the medial side of the heel portion. From ball-to-foot and toe-off, the load generally moves forward to the forefoot region of the boot and diagonally from the inside to the outside of the boot. Thus, during heel-off and toe-off, the primary load is on the outside of the forefoot until the wearer pushes off with the toes. Properly designed boots or other shoes may facilitate the gait cycle of the wearer while providing stability and support to the foot and leg of the wearer. U.S. Pat. Nos. 6,484,420, 6,757,990, 8,789,292, and 9,591,888 disclose significant advances in footwear technology that enable lightweight footwear assemblies while maintaining a very stable platform. U.S. Pat. Nos. 6,484,420, 6,757,990, 8,789,292, and 9,591,888 are incorporated herein by reference in their entirety. The lightweight shoe assembly adopts a configuration in which at least a portion of the lateral and medial peripheral flanges of the upper are stitched to the insole at the phalanges and/or heel portions, but they are not stitched to the insole throughout the arch portion. In addition, the lateral and medial peripheral flanges of the upper are wrapped around the lateral peripheral edge of the insole in the arch portion, and the medial peripheral flange of the upper is wrapped around the medial peripheral edge of the insole in the arch portion. In addition, lateral and medial peripheral flanges are secured to the bottom surface of the arch portion of the inner sole. This configuration provides a very lightweight and stable platform, although there is still room for improvement in the selected shoe. Drawings FIG. 1 is a side view of a shoe assembly in accordance with an embodiment of the present technique. Fig. 2 is a perspective partially exploded view of the shoe assembly of fig. 1. Fig. 3A is a cross-sectional end view taken generally along line 3A-3A of fig. 1. Fig. 3B is a cross-sectional end view taken generally along line 3B-3B of fig. 1. Fig. 4 is a bottom view of the shoe assembly of fig. 1. Detailed Description In accordance with embodiments of the present technology, footwear assemblies having a upper securely attached to a reinforced insole board via adhesive and stitching stitches, and related methods for using and manufacturing such assemblies, are described in detail herein. The footwear assemblies described herein include features that increase stability in the heel and arch regions, and transitions that allow the forefoot region to be compliant. In this regard, some configurations are capable of providing stability and support during heel strike and ball strike of a user gait cycle while increasing compliance, energy transfer, and/or comfort in transitioning from ball strike to heel-off and toe-off. In one embodiment, for example, a shoe assembly includes a upper coupled to a sole assembly having a U-shaped first insole board coupled to a full length dual insole board having multiple stiffness, and a transition member attached to the dual insole board at a transition between areas of different stiffness, such as in the arch and heel areas of the shoe, respectively. Thus, the transition member spans the transition region of the dual mode insole board and extends at least partially from the arch
