This invention relates to a device to sole and
heel footwear, including worn footwear, and it
relates to the rehabilitation and repair thereof.
Its principal object is to provide improved
means for moulding a new sole and new heel of
rubber or plastic material on and a?ixing the
same to an article of footwear whether that ar»

varies from a relatively ,wide heel portion which
tapers gently at the shank portion to a relatively
narrow sole portion. Band II] is provided at pre
determined intervals with small holes H whose

is a transverse band 2?, which extends at both
ends to band 10. Between said transverse band
and the sole portion proper is a shank core 39
which occupies the space corresponding to the
space formed beneath the shank of a conven
tional shoewhen that shoe is placed upon a flat
surface; The shank core comprises a pair of

spaced longitudinally extending members 3| and
32 respectively which are mounted between a pair
of spaced upper shank plates 33 and 33:11, re

plates 33 and 33a have a pair of side walls 35 and
