As shown on the drawings: a The "illustrated embodiment of the instant "in- "vention consists 'inygeneral of a body portion, generally indicated by numeral 5, and an attaching element or band generallyindicated by-num- 'erali secured to the bodyportion '5 adjacent one When the device is applied over a region of the -metatarso-phalangeal joint at the J first metatarsal "head, the attaching band 6 :is

disposed over the great toe I of the foot, and the loody portion 'ofthe device extends rearwardly, overlying the a'fili'c'tion. ith "the attaching b and icircumscribing the 'great toe, nothing else is concavo-convex shield made up of a layer 8 of cushioning material, preferably foam latex. This layer of cushioning material is covered by a relatively thin latex sheet 9 having a smooth external surface. The latex sheet 9 may well be a thin rubber sheet of the character utilized for dental dams. cemented to the external face of the shield structure 8, or it may be vulcanized thereto if so desired, and closes the pores of the foam latex on the outer side. Obviously, the thin sheet 9 prevents any adherence to the stockings of a user when the device is in place on the foot, and permits the stocking to be freely and easily drawn onto the foo-t with the device in place.

The securing band 6 is formed in the same way and made of the same material as the concavo-convex shield 8, and includes an inner layer of foam latex l0, covered by a thin latex sheet I I. Thus this band is elastic and may readily be attached over the toe of the user, without any discomfort. If so desired, the band may be integral with the shield.

For ventilation purposes the shield is preferably provided with 'one or more apertures or openings I2 therethrough, and these openings may be disposed in any desired location.

A flange-like element 13, also preferably made of foam latex, and of substantially the same thickness as the portion 8 of the shield, is mounted inside the shield. In the preferred form of structure as seen clearly in Figs. 3 and 4, this flange-like member l3 possesses the same general oval contour as the shield itself and is provided with a central aperture or opening M which may satisfactorily be of oval contour. This aperture, of course, receives the affliction, or at least the most sensitive part of the aflliction. As seen best in Fig. 4, the flange-like element i3 is substantially flat in character, and is secured to the interior face of the shield only at the edge portion of the flange, as indicated at 15. This securement may be by way of cementitious material or otherwise. With securement being at the edge portion of the flange member only, there will be a definite space [6 between the flange and the shield, this space increasing inwardly from the line of securement.

Were the flange l3 secured over its entire face by cementitious material to the inner face of the shield, much of the resiliency and cushioning properties of the device as a whole would be lost, but with the space l6 present, the cushioning function of the device is greatly enhanced.

Added to this advantage. it will be noted that there is no considerable thickness of material directly over the afliiction at-any time during use of the device. The flange may be bent so that a greater area of it actually contacts the inside face of the layer 8 of the shield when the device I is applied to the foot of the user, but by virtue of the flange, any pressure from an article of footwear or the like is transferred from the affliction to the healthy tissue surrounding the afiiiction, the affliction or the most sensitive partof it extending through the opening M in the The thin sheet 9 is preferably 4, flange l3 and being further protected by the shield itself.

In the illustrated instance, the ventilation openings I2 in the shield are shown as communicating with the space 16 between the shield and the flange, but it will be imderstood that it is not necessary to so locate the openings.

Since the instant invention is made of foam rubber, the entire device is extremely light in weight, yet by virtue of its construction is capable of providing more than adequate cushioning power to elfectively transfer pressure from an affliction to surrounding healthy tissue. Further, the device presents an appearance that at once inspires confidence in the prospective user that the device will adequately perform its function and not be uncomfortable even when disposed in the wearers regular article of footwear, because of the relatively small space occupied by the device. It should also be noted that the device is long lasting, and may readily be laundered or otherwise cleansed whenever desired. In use the device is extremely simple, it being merely necessary to slip the elastic loop 6 over the toe, and the device will automatically seat itself properly over the affliction, with the more sensitive part of the afiliction received inside the opening of the flange l3.

It will be understood that modifications and variations may be effected without departing from the scope of the'novel concepts of the present invention.

I claim as my invention:
