Article of footwear with modifiable sole

Abstract

An article of footwear is provided with a modifiable sole having raised projections and / or drain guides. The raised projections are capable of receiving a threaded screw to increase the traction between the sole and an underlying ground surface. Information-conveying indicial markings can be provided on the base surface and associated with the raised projections, the indicial markings conveying information regarding the type of threaded screw that can be received by the raised projections and where to attach a threaded screw to the sole. The drain guides indicate where drain holes can be formed in the sole to enhance drainage

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to footwear, and more particularly to a sole for an article of footwear.[0002]Conventional articles of footwear include an upper and a sole secured to a lower surface of the upper. The upper provides a void that receives a person's foot and positions the foot with respect to the sole. The sole may provide traction or cushion for the foot under a variety of conditions, e.g., walking, running or standing, or a combination thereof, and commonly includes a midsole and an outsole. A footbed or insole typically is disposed in the interior of the upper for additional cushion.[0003]The general function of the sole is to provide a layer of protection for the wearer's foot. The sole can be designed not only to protect the foot from contact with the ground, but also to provide improved comfort and support for the foot. There is an ongoing effort to develop new and improved sole constructions that provide optimal performance across ...

AI Technical Summary

Benefits of technology

The present invention is a shoe that allows users to customize it by adding screws or drain holes, which are accompanied by indication marks. This makes it easy for users to modify the shoe for different terrains and conditions. The main technical effect of this invention is that it provides a high degree of customization with a conveniently modifiable sole.

Problems solved by technology

Conventional lug constructions can suffer from a number of typical problems, including that lugs are often not designed for multi-surface or multi-condition use.

Such bores can collect dirt and mud when traction devices are not attached.

Similarly, users have added drain holes to footwear not originally designed to accommodate drainage.

Because such footwear is not configured for the addition of screws or drain holes, users must take a trial-and-error approach in the placement of screws and drain holes, often damaging the footwear in the process.
