This invention. relates to‘ footwear, and more mg two shown on opposite sides of the sandal. '
especially it relates to rubber bathing sandals. , The end portions of straps M are formed with
The chief objects of the invention are to pro
vide improved molded rubber bathing sandals;
5 to obviate the use of forms or lasts in the manu
facture of rubber sandals; to provide a sandal
consisting of a single unitary structure; to pro
vide a sandal of such character that one sandal
of any size is adaptable to the requirements of
10 several foot sizes, thereby reducing the amount
of equipment required for the manufacture
thereof, and reducing the number of sizes to be
manufactured; to provide a ‘sandal that is in
respective apertures I5 that are reinforced by re
vspectivebosses IG' concentric therewith. ‘Ob-‘
viously the number and arrangement of- the Cl
straps l4 may be varied to suit different styles
and sizes of footwear.
Projecting laterally from each side of the shank
portion of the sandal structure are respective
instep portions l8, l8, which portions have front
and side margins disposed substantially at right
angles to each other, and are formed with re
spective apertures i9 reinforced by bosses 20 at

The insole portion of the structure designated
II is coextensive with the outsole I0 and is desig
nated £3. The portion thereof referred to as the
upper comprises short straps I4, l4 projecting
55 from the forward part of the structure, there be
utor folds them preparatory to sale.
In the operation of folding the sandals to ?n
ished form, suitable rubber cement ?rst is ap
plied to the roughened portions 23 and 27 of the
respective straps 2i and 25. Then strap 25 is
?exed upwardly, and the end portions of the two
straps 2| are buttoned onto button 28 of strap
25 by means of the apertures 22 in said straps.
Then the end portion oflstrap 25 is folded over
the end portions of-straps 2| and button 28 in
serted through aperture 29 of said strap 25. The
strap 25 is of such length that its end portion
may be adhered to itself, below the straps 2|, as
shown in Figure 4. The‘ arrangement is such
that the button 28 effects the accurate position

means at the forward end thereof, a rearwardly

region thereof, said instep portions being formed
with respective rearwardly extending straps, the
terminal portions of the latter and the heel strap
being‘ formed each with an aperture; and the heel
strap being formed solely on one face thereof with
