Definitions

• Shoe adapted to receive an inner sole The present invention relates to footwear and in particular to a shoe adapted to receive a variety of orthopaedic support devices in the nature of inner soles.
• Great advances have recently been made in relation to footwear provided with therapeutic inner soles and insoles insofar as inner soles having upper surfaces of varying shapes and configurations and textures have been found to have beneficial effects not only upon the wearer's feet bu varying massage effects which can be obtained via such inn soles have been found to benefit the physical and mental we being of the wearer in areas far removed from merely the feet. For example nodular surfaces and foams of varying densities have been used.
• Such inner soles as last mentioned may vary widely in shape and configuration although in order to work effectiv most of such devices are necessarily of a depth of 4 mm or more.
• inner soles having a depth of 4 mm or more.
• one inner sole may be removed and replaced by another has obvious advantages insofar as inner soles of different profiles designed to support or massage different areas of the foot may be introduced to the shoe and of course inner soles which have lost their resilience or worn out may be readily replaced.
• an article of footwear including a nest of unobstructed space within the article of footwear and not separated from the area intended to receive a wearer's foot; said article of footwear including a wall around the periphery of a sole of said article, thereby defining said nest, said nest being adapted to releasably hold a therapeutic or other inner sole. Due to practical considerations nests of 40 mm or more depth would be impractical and result in unsightly articles of footwear.
• Fig. 1 is a longitudinal section through a clog in accordance with the present invention showing the nest without an inner sole insert.
• Fig. 2 is a transverse section through the article of Fig. 1 a line x-x of Fig. 1;
• Fig. 3 is a longitudinal section of the article of Fig. 1 showing one type of therapeutic inner sole;
• Fig. 4 is a transverse section through the article of Fig . 3 along l ine y-y of Fig . 3.
• Fig. 5 is a longitudinal section of the article of Fig. 1 showing a further type of inner sole in place;
• Fig. 6 is a transverse section through the article of Fig. 5 along line z-z of Fig. 5;
• the clog 1 comprises a sole 2 and upper 3 for receiving a wearer's foot (not illustrated).
• the sole 2 comprises a lower treaded portion 4 and in an upper portion thereof, a nest 5 defined by the protrusion or wall 6 which extends from the sole 2 around the circumference of the sole 2. It will be understood, that as Fig. 1 illustrates a longitudinal cross section through a clog 1 that the nest 5 extends from the rear or heal portion 7 of the clog 1 through to the toe 8 of the clog 1.
• the upper 3 of the clog 1 is secured into position in the shoe by an overlapping portion 9 thereof being "tucked in” under an insole 10 which secures the upper 3 relative to the sole 2.
• This overlapping portion 9 extends along the periphery of the insole corresponding to those portions of the upper 3 which come into contact with the insole 10.
• Additional securing means such as are common to the trade, for example, gluing and the like, can be utilised to secure the insole 10 and upper 3 relative to the sole 2.
• the wall 6 about the periphery of the sole 2 is of sufficient height to provide a nest 5 of at least 4 mm in depth above the insole 10.
• the nest 5 is capable of receiving various inner soles, such as therapeutic type inner soles as depicted by item 11 in Figs. 3 to 6.
• One advantage of the nest 5 in accordance with this invention is that the inner soles 11 utilised therein, having substantial thickness and consequently stability, will not buckle, ride up the shoe, or move within the shoe, in a manner in which the inner soles would normally do. If such shoes are designed specifically with a therapeutic effect in mind, it is important that such provision be made in order that the foot be correctly located and allow the proper therapeutic effect to be exerted upon the foot inserted in the clog 1 or other article of footwear.
• Conventional shoes may vary somewhat in height about the area of the arch 12, but for any given size of shoe, there is usually less than 4 mm variance in height between virtually all makes of shoes in the vicinity of the region adapted to receive the toes namely toe 8. That is, the difference in height from the toe to the arch region of most conventional " shoes would be less than.4 mm.
• footwear can be made to appear more conventional by providing the article of footwear 1, with a skirt 101 which is located between the wall 6 and upper 3 extending around the lower part of the shoe and which is integral with the sole 2 of the shoe.
• This skirt lOf disguises some of the excess height which is essential in an article of footwear 1 which is to incorporate the present invention.
• the inner sole 11 located in the nests 5 have, in cross section, various contours. However, in order to sit in the nest 5 and be located and releasably held, the height 13 of the edge or periphery of the inner sole 11 is at least 4 mm in height.
• tread patterns may be utilised to provide more effecient gripping, and various styles can be incorporated in the uppers.
