Benefits of technology

[0014]Due to the low density of the lower layer, the layer is particularly susceptible to damage from the elements. Outside elements, if allowed to contact the lower layer or seep in between the layers may cause chemical reactions and lead to the breakdown of the midsole. In particular, outside elements such as extreme heat or cold, hydrolysis, ozone oxidation, UV radiation, and acid rain can cause a chemical breakdown of the elastomeric materials used for midsoles, thus reducing the efficiency and lifespan of the midsole.

Embodiment Construction

[0026]The invention will now be described with reference to the preferred embodiment shown in FIG. 1. This embodiment shows a midsole 101, the upper layer of the midsole 100, the lower layer of the midsole 102 and the film 104. As used herein, “above” and “below” refer to relative locations of identified elements when a shoe and thus the midsole is in its normal, upright position as shown in FIGS. 1 and 5.

[0027]The midsole 101, as shown in FIG. 1, comprises an upper layer 100 and a lower layer 102. The upper layer 100 may comprise a plurality of sub-layers. The upper layer 100 has a top surface 113 substantially opposite a bottom surface 115. The upper layer 100 has a peripheral wall 103. The lower layer 102 has a top surface 117 substantially opposite a bottom surface 121. The lower layer 102 has a peripheral wall 105. As shown in FIGS. 1 and 5, when the midsole is in its normal, upright position, the lower layer 102 is below the upper layer 100.

Abstract

A midsole of a shoe with multiple layers in which at least one of the layers is wrapped in film in order to protect it from the elements, provide stability and also to provide some visual features.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to the structure of a midsole for a shoe. More particularly, the present invention relates to a midsole that has a soft layer wrapped in a protective, stabilizing and / or decorative film.[0003]2. Description of the Related Art[0004]Shoes are comprised of an upper, midsole and outsole. Shoes are designed for many purposes—from protection on the job, to performance during athletic activity on the track or court, to special occasions and everyday lifestyle. In order to achieve these purposes, shoes are made with different types of uppers, midsoles and outsoles that enable them to properly suit the activity. Midsoles are an integral part of the shoe and provide stability and cushioning to the user of the shoe.[0005]A shoe midsole may be designed with various considerations. Some of those considerations present limitations and disadvantages. In some applications, the midsole must have a soft elem...
