Embodiment Construction

I. Overview

[0018]Footwear constructed in accordance with a preferred embodiment is shown in FIGS. 1-6 and generally designated 10. The footwear 10 includes an upper 20 joined with a midsole 30, which is further joined with a midsole frame 50, which is joined with an outsole 90. A closure 40 can be joined with the midsole frame 50 and / or upper 20 to further secure the footwear on the foot of a wearer. The midsole frame 50 can include a forefoot frame base 52 and a heel frame base 54, which are joined by an intermediate frame section 60. Optionally, a plate 70 can be included in the footwear between the midsole 30 and the midsole frame 50. The midsole frame 50 and outsole 90 can each include voids SO, 82, 84 and 91, 92, 94, which are generally aligned with one another, respectively. When included, these voids can provide improved flexion of the footwear along the longitudinal axis A of the footwear to reduce fatigue on the wearer's foot.

Abstract

A footwear construction including a midsole frame having a forefoot base, a heel base and an intermediate frame section that connects the forefoot base and the heel base. The forefoot base and heel base can be separated from one another by a frame void. The forefoot base can include at least one forefoot base void extending across the width, of the footwear to improve flexibility of the footwear. The construction also can include a midsole including a lower surface housed at least partially within and / or joined with the midsole frame, with the midsole frame forefoot base and a heel base separated from one another below the midsole lower surface by the frame void, and connected above the lower surface by the intermediate frame section. Where the construction includes an outsole, that outsole can define an outsole forefoot void, which can be aligned with the forefoot base void.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to footwear and, more particularly, to a footwear construction and a method for making the same.[0002]In the footwear industry, there is an ongoing effort to produce footwear that provides a high level of stability and support, while maintaining exceptional comfort. This effort is heightened in the design of high performance footwear, such as watersport, hiking, mountaineering, multisport and rugged outdoor walking footwear. To minimize the effects of travel over jagged, rugged or uneven surfaces high performance footwear is frequently provided with components that provide torsional stability (e.g. resistance to twisting forces) and longitudinal stability (e.g. resistance to linear forces).[0003]Conventionally, stability and comfort have been competing characteristics. Efforts to improve stability and support typically result in a reduction in flexibility in the shoe, and subsequently comfort. A common technique for impr...
