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.
