1 Claim.

This invention relates to overshoes of waterproof and elastic rubber material lined as with y textile material for the purposes of reinforcing and protecting the rubber and helping to maintain the shape of the shoe and also for the sake of comfort to the wearer. Unlined overshoes have been found objectionable to some wearers as giving a cold feeling and in some cases being subject to snagging and other injury.

Lined overshoes have been naturallylimited in stretchability which has usually required the provision of an enlarged top opening to make it possible to slip the overshoe over the shoe, and this in turn has complicated the problem of preventing the overshoe from slipping off the shoe too easily. The prior overshoes, in order to resist slippage from the heel of the shoe have usually had stiffening means built into the overshoe, such as a stiff quarter section adapted to snap upward into position after depression of it as the shoe enters the overshoe. Occasionally it has been necessary to apply a cementitious substance to the face of the overshoe lining contacting the back or counter of the shoe in an endeavor to overcome the insuicient ability of the overshoe to cling to the back of the shoe.

An object of this invention is to provide a lined overshoe with means for permitting easy donnin-g .and doiiing together with a close clinging fit of the heel portion of the overshoe upon the back of the shoe. Further objects are to provide these results substantially without altering the appearance of the overshoe, and to provide for reducing the weight of the overshoe without sacrilice of its protective qualities. These vand further objects will be apparent from the following description, reference being had to the accompanying drawing in which:

Fig. 1 is a side elevation of an overshoe constructed in accordance with and embodying the invention.

Fig. 2 is a section taken along the line 2 2 ci' Fig. 1.

Fig. 3 is a section taken along the line 3 3 of Fig. 2.

Fig. 4 is a section taken along the line 4 4 of Fig. 3,

In the drawing the invention is illustrated as applied to a mans overshoe, but it will -be understood that the invention is applicable to overshoes of other types and constructions.

An upper I0 has a lining I I of textile material .and an outer layer of elastic rubber material I2.

The overshoe may have a trimming strip I3 of elastic rubber around its top opening and a reinforced sole, shank and heel piece I4 including suitable heel-bottom stiffening means I5 and an insole I6.

The outer rubber layer I2 extends continuously around the heel section of the overshoe, but in accordance with the invention the lining II terminates short of the rearmost portion of the heel section in margins I1, I1 so spaced apart as to permit considerable stretchability of the heel section of the overshoe between such margins. Preferably the margins Il, I1 are disposed approximately at the forward portion of the heel section so as to make all or a large part of the heel section of the overshoe stretchable. To the end of providing the desired rmness of the heel section without restricting unduly its stretchability a piece I 8 of rubber material may `be disposed in the space between the margins I1, Il of the lining and preferably overlapping such margins in iirm adhesive attachment to the shoe, the rubber piece I8 serving to obviate the necessity for the usual quarter stiffener used in overshoes.

For further stiiening the heel section of the overshoe upper without objectionably reducing the stretchability thereof another piece of fabric I9 serving as a collar piece may be applied with an outer layer 2B of rubber, this fabric piece being of stretchable netting and extending only partly over the area of the heel section of the overshoe, the margin of such fabric terminating at ZI.

By the construction of this invention a lined overshoe is made possible wherein the opening can be as small or smaller than the corresponding part of the shoe of the wearer, it being unnecessary to provide the looseness heretofore necessary in overshoes of this class for making donning and doilng possible. Merely pulling back or widening the heel section of the overshoe by stretching it makes donning and doing convenient. Also when the overshoe is in place the elasticity of the heel section provides a capacity of such section to cling to the shoe of the wearer, effectively resisting removal. If desired, this clinging function may be enhanced by providing a roughened or knurled inner surface on the rubber piece I8, as shown at 22.

In outward appearance, and in ruggedness and rmness of the construction, the overshoe resem- ,bles the stilTer less elastic constructions used heretofore, and at the same time the advantages provided by the improved construction of the heel section as hereinabove discussed are available.

Variations may be made Without departing ward part of the shoe over saidgheel-receiving 10 portion, a fabric lining secured to the inner face of said outer layer forward of the heel portion of the upper and terminating at the heel .portion with the edges of said lining extending upward from the bottom of the heel-receiving portion at each side thereof, the heel portion of the upper having a stiening layer spaced rearwardly of said edges of the lining and connected to said lining by an extent of said elastic outer layer Aproviding stretchability of the heel-receiving portion for donning and doiiing the overshoe.
