Application April 1, 1943, Serial No. 481,471 10 Claims. (01. 36-42) This invention relates to footwear safety demay be provided with reinforcing ribs '20. The cover I8 extends upwardly and rearwardly as shown in order to protect the ankle. On the under side of the'main cover 18 is a loop strap the front of the shoe.

As shown in Fig. 1 there is clearance 54 between the guard an To apply the guard to the shoe the toe arch clips 8 are spread by means of the finger grips I: ind the guard is then slid horizontally along the toe cap's welt. The main cover is and the rear arch 24 are depressed over the instep I untilthe lower edge of the arch 24 seats on the shank welt. Zlhe link II is then positioned to contact the front of the heel crosswise and the fastener 32 is hooked over the hasp II. The

springs 48 are pulled up by means of strap 44 and buckle ii to secure the guard in position with the ledges resting on the sole or welt of the shoe.

It will be seen that the main cover It has been L leased and the fastener 32 disconnected from the hasp 34 to enable the under slung link to be swung back. The rear arch 2| is then lifted above the instep and the guard pushed forward until the toe arch clips 8 clear the toe of the shoe.

While one embodiment of the invention has been shown and described, it is understood that other modifications and adaptations may be made without departing from the scope of the attached claims.
