In Fig. 1 a heel member lll is shown affixed to the base of a shoe. The heel member IB con# sists of a single metal strip l2 and a lift member I4. A llet reinforcing member I6 is welded or otherwise aiixed at the neck of the heel structure to reinforce the curved column of the metal arch l2 as shown in Figs. 2 and 3.

Figs. 1, 2, and 3 show theheel bent around a transverse axis. A channel (indicated at I8 in Figs. 4 and 5) is formed longitudinally in the heel. Figs. 2 and 3 show that the depth or pitch of the longitudinal channel increases as the curve around the transverse axis is accentuated. Fig. 4 shows the depth or pitch of the longitudinal channeling relative to the Width of the metal strip atrthis section. Fig. shows thesame channeling (i8) as in Fig. 4 but the pitch of the channeling is increased owing to the decrease in the width of the metal strip.

A toplift 22 is affixed to the base of the heel. Fig. 6 shows one way in which the lift can be Wood or composition material 20 is affixed adhesively to the base of the heel member l2. A toplift 22 is mounted on the wood or composition material 2U by means, for example, of nails driven into the material 20 or the lift 22 can be mounted adhesively to the material 2U. If the metal strip l2 is to be covered withv cloth or leather or the like, the covering material 24 can be inserted between the composition material 20 and the metal member I2 as shown at 25.

' of the inverted S-curve to assist rigidity.

Figs. 9 and 10 show double longitudinal channeling at the top of the heel structure. This double channeling narrows into a single longitudinal channel as shown in Fig. 10. I nd that the double channeling is particularly useful in giving a rigid structure Where the conguration of the heel structure follows an inverted S-curve.

In Fig. 11 I show a relatively narrow strip which has correspondingly greater depth in the longitudinal channel, as shown in Fig. 12. Fig. 11 also shows a heel structure following the S-curve and having a channeled shelf portion.

This application is a continuation in part of my design applications Serial Numbers D81,941 and D-81,940, led December 22, 1938.

I claim:

1. A metal heel for a shoe, comprising a strip of metal, said strip having portions bent around transverse axes and portions bent around longitudinal axes, a longitudinal channel formed thereby in the transversely curved strip, and a lift axed at the base of said strip.

2. A metal heel forv a shoe, comprising a strip of metal, said strip having portions bent around transverse axes and portions bent around longitudinal axes, a longitudinal channel formed thereby in the transversely curved portion at points Where the metal strip is bent around transverse axes, and a lift aixed to the base of said strip.` f

3. A metal heel for a shoe, comprising a strip of thin metal, said strip having portions bent around transverse axes and adjacent portions bent around different longitudinal axes to form two longitudinal channels in the transversely curved portion at points Where the transversely curved strip is bent around its transverse axes and a lift affixed to the base of said strip.

4. A metal heel for a shoe, comprising a tapered strip of metal having portions bent around transverse axes and portions bent around longitudinal axes, a longitudinal channel formed thereby in said transversely curved portion, the pitch of said longitudinal channel increasing as the width of said strip decreases, and a lift affixed at the base of said strip. i

5.,A metal heel for a shoe, comprising a strip of thin metal, said strip having portions bent around transverse axes and portions bent around longitudinal axes, a longitudinal channel formed thereby in said transversely curved portion, a fillet mounted at the base of said strip, and a lift affixed yto the base of said strip.

6. A metal heel for a shoe, comprising a strip of metal, said strip having portions channeled around transverse axes and portions channeled around longitudinal axes, a longitudinal channel formed thereby in the transversely curved strip, a shelf-like portion channeled longitudinally at the top of said strip for attachment of the heel to the shoe, and a lift affixed at the base of said strip. l
