fig1 - 4 illustrate a footwear protecting sock 10 according to a first embodiment of the present invention . the footwear protecting sock 10 includes a flexible main sleeve member 12 and a flexible , protective sleeve member 14 coupled to the main sleeve member 12 . the main sleeve member 12 includes an opening 16 at a first end thereof which is adapted to receive a user &# 39 ; s foot and leg therethrough . the flexible main sleeve member 12 additionally includes a hollow body portion which includes a toe - receiving portion 18 , a heel - receiving portion 20 and a leg - receiving portion for receiving the ankle and calf of the leg , depending on the height of the main sleeve member 12 . the hollow body portion is formed of a lower portion 24 , which includes the toe - receiving portion 18 , heel - receiving portion 20 and an upper portion 26 which is sewn to the lower portion 24 as best shown in fig2 and 4 . this construction will minimize the seam 27 as viewed from the exterior of the sock 10 and provide a quick , easy procedure for producing the sock 10 . additionally , with this construction , the flexible , protective sleeve member 14 is formed integral with the lower portion 24 of the main sleeve member 12 in a conventional fashion as in ordinary sock construction . elastic gripping members 28 are provided in the upper portion 26 substantially surrounding the opening 16 and are adapted to secure the sock 10 to the leg of the user as illustrated in fig1 . the elastic gripping members 28 are formed in a conventional fashion such as elastic members sewn into the fabric of the sock 10 . the flexible , protective sleeve member 14 is coupled to the hollow body portion of the sleeve member 12 as discussed above . the protective sleeve member 14 includes an opening 30 at a first end thereof which is adapted to surround and receive an upper portion of the user &# 39 ; s footwear as shown in fig1 . elastic gripping members 32 are incorporated in the flexible , protective sleeve member 14 substantially surrounding the opening 30 and are adapted to secure the sock 10 to the upper portion of the footwear as shown in fig1 . the elastic gripping members 32 may be substantially the same as the elastic gripping members 28 discussed above and can be formed in a conventional fashion . in operation , the sock 10 is placed on the foot of the user with the user &# 39 ; s toes and heel received in the toe - receiving portion 18 and heel - receiving portion 20 in a conventional fashion by being inserted through the opening 16 . the user &# 39 ; s footwear is placed over the sock 10 and the protective sleeve member 14 is overlapped over the upper portion of the user &# 39 ; s footwear , as shown in fig1 . within the context of the present application , footwear should encompass any type of shoe , boot or cast as will be described hereinafter . the footwear protecting sock 10 illustrated in fig1 - 4 of the present invention is particularly suited for use in the construction industry with construction work boots as described above . consequently , it is anticipated that the protective sock 10 would be made out of a fabric material such as cotton or the like as is well known in the hosiery art . the sock 10 is also particularly relevant to snow boots as discussed above . consequently , the fabric material for making the sock 10 may also be a waterproof material to assure that the user &# 39 ; s foot is maintained in a dry condition . the sock 10 of the present invention additionally provides the ability to change the overall appearance of the sock 10 . specifically , sock 10 of the present invention may be worn as a conventional sock with the protective sleeve member 14 against the user &# 39 ; s leg as shown in fig3 . the appearance of the sock 10 will be dictated by the exterior surface of the protective sleeve member 14 . an alternative design can be presented by rolling the protective sleeve member 14 down over the top of the footwear , as illustrated in fig1 in which event the interior surface of the protective sleeve member 14 and the exterior surface of the upper portion 26 would define the appearance of the sock 10 . the exterior surface of the upper portion 26 and the interior surface of the protective sleeve member 14 may be formed of complementary designs , colors , or a logo 35 as shown in fig1 and , importantly , this may differ significantly from the appearance presented on the exterior surface of the protective sleeve member 14 . this configuration will allow the sock 10 of the present invention to present multiple versions of distinctly different appearances . this feature of the sock 10 of the present invention may be particularly well received by children . when placing a limb in a cast , the area to be wrapped with a hardening cast is generally covered with a gauze - type material prior to placement of the cast so that the cast is not formed directly on the skin . the sock 10 of the present invention is particularly well suited for use in place of the gauze for a hardened cast on the foot , ankle or lower leg of the user . where appropriate , the foot and leg can be placed into the sock 10 as described above . a hardening cast is installed over the hollow body portion of the sock 10 . after the cast is set , the upper end of the cast would be overlapped with the flexible , protective sleeve member 14 and the protective sleeve member 14 secured to the cast through the resilient gripping members 32 . the sock 10 of the present invention provides an intrusion - proof cast , preventing debris and other material from entering into the interior of the cast . this is particularly important as the cast stays on , and the muscle atrophies from lack of use , decreasing in size . the atrophy of the muscle will increase the gap between the edge of the cast member and the skin . the sock 10 of the present invention can maintain the cast in a sealed condition despite such muscle atrophy . additionally the protective sleeve member 14 can easily be restored to a non - overlapped position to permit air to enter the gap when desired . fig5 illustrates protective hosiery 10 &# 39 ; according to a second embodiment of the present invention and is particularly adapted for installing an intrusion - proof cast 50 on an arm or upper leg of the user . the protective hosiery 10 &# 39 ; is substantially the same as the sock 10 described above except that the second end thereof includes an opening 16 &# 39 ; formed by an additional portion 26 &# 39 ; with gripping members 28 &# 39 ; therein . a second protective sleeve member 14 &# 39 ; is attached at the second end with an opening 30 &# 39 ; and resilient gripping members 32 &# 39 ; provided therein substantially the same as the protective sleeve member 14 , opening 30 and gripping members 32 described above . the protective hosiery 10 &# 39 ; is adapted for use with a cast on the arms or upper legs of the user where the limb to be set is positioned all the way through the protective hosiery 10 &# 39 ;. both protective sleeve members 14 and 14 &# 39 ; will be overlapped around one end of the cast member to protect both respective sides of the cast member as illustrated in fig5 . it will be apparent to those of ordinary skill in the art that various changes may be made to the present invention without departing from the spirit and scope thereof . consequently , the scope of the present invention is intended to be defined by the attached claims .
