Benefits of technology

[0012]The present invention is drawn generally to footwear, and more specifically, to footwear having reduced noise and impact characteristics for wearing on a hard floor, for example, tile, wood, or other hard material. Noise generated by impact of the foot falling, striking or impacting onto a hard floor is reduced by an outsole with predetermined

However, no such footwear has been proposed for use in an indoor casual or recreational environment having this function.
Also known are footwear intended for use in a casual or recreational environment, such as slipper socks described in U.S. Pat. No. 5,617,585, which discloses a combination of sock and a rubber sole, for providing comfort and foot protection, but not addressing the problem of noise reduction.

Embodiment Construction

[0022]Referring now to the drawings, it should be appreciated that like numerals refer to like parts and to corresponding parts throughout the several views and parts having similar functions have similar numbers, but having the prefix of a different hundred series. A first embodiment of the present invention sock shoe 10 is shown in FIGS. 1 to 5, which comprises an outsole 30, an insert 60 and a shoe upper 90. Generally, shoe upper 90 is attached to the outsole 30, and insert 60 is placed within outsole 30 and retained within the outsole 30 by the upper 90.

[0023]Outsole 30 may be made with materials traditional thermoplastic elastomers (TPE) as well as “green” polyethylene rubbers which are made from any natural resource that can be processed using biopolymer chemical engineering. Ideally, these have a pre-specified hardness, outsole 30 being hard enough to give protection to the foot and simultaneously to withstand normal wear and at the same time reducing the noise generated by f...

Abstract

The present invention is drawn generally to footwear, and more specifically, to footwear having reduced noise and impact characteristics. According to the invention noise generated by the impact of the footfall when in contact with hard floors is reduced by an outer sole with certain hardness and a sound reducing insole which comprising a material of high indentation forced deflection (IFD) weight having a minimum thickness of ¼ to a maximum ¾ inch, and an optimal thickness of about ½ inch. Also, the footwear comprises an upper portion attached to the outer sole to provide comfort and foot protection.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The disclosed invention claims the benefit under 35 U.S.C. §119 (e)(1) of provisional application Ser. No. 61 / 838,848, filed on Jun. 24, 2013, the entire specification of which is incorporated by reference as if fully set forth herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention is drawn generally to footwear, and more specifically, to footwear having reduced noise and impact characteristics when walking on hard floors.[0004]2. Background Art[0005]Noise reducing footwear has been proposed for some time and especially for use to reduce noise outdoors. There are several kinds of noise reduction footwear used for outdoorsmen. The general idea is to use sound absorbing materials as a bottom sole of the footwear, as shown in U.S. Pat. No. 5,799,418 and U.S. Pat. No. 5,1686,43. However, no such footwear has been proposed for use in an indoor casual or recreational environment having this function. The noi...
