Such devices ?nd wide application in many
?elds where it is necessary or desirable that
slipping between the sole of the shoe and the
walking surface be avoided. Hill climbing, lum
bering, walking on ice and various sports, as
10 golf and baseballyare examples of some of the
?elds in which the present invention has applica
tion.
It is an object of the invention to provide an
antislipping device which is simple in construc
tion and economical to produce.

It is another object of the invention to provide
an antislipping device which is readily adjustable
to ?t shoes of various sizes.
Another object of the invention is to

applied to a shoe but which when’appli‘ed to the
shoe will automatically move into secure opera

maintained in operative relationwith the shoe
by means of a resilient connection between the
device and a means engaging the shank portion
of the shoe sole.

Before describing the present improvements
and mode of operation thereof in detail it should
be understood that the invention is not limited
to the details of construction and arrangement
of parts shown in the accompanying drawings,

ferred "embodiments, since the invention is ca
pable of other embodiments, and the phraseology
employed is for the purpose of description and
not of limitation.

plurality of notches 51 therein adapted to receive
the stop ?ange 55 and thus lock the bars from
