the toe portion or band 39. This arrangement permits
the support of the ankle together with the heel portion
of the foot. The toe band 39 and the counter portion
41 may be connected together by means of t-he strap and
slot arrangement.
The two blocks 20 and 21 are spaced from one an
other. They may be variantly spaced longitudinally of
support 10 and may have variant lateral and angular posi
tions relative to one another and to the support `10.
They are retained in a fixed position by means of the
bolts 16 and 17 to support the foot in any predetermined
position or angle -for the correction of the deformities.
From the above description it will be seen that the
device will retain the foot at any selected disposition rela
tive to the thigh and lower leg by means of the straps 28,
32 and 37, the strap 28 being applied to the thigh and
members on the forward and rearward portion of said
foot support, each foot restraining member including a
block and a holding member positioned thereon, said
holding member being formed and adapted to grip and
hold a portion of the foot on said block, means mounting
each restraining member on said foot support for ad
justment laterally thereof independently of each other and
`for rotary adjustment about an axis extending generally
perpendicular for the general plane of said foot support,
to thereby enable selective twisting of the front and rear
portions of the user’s foot relative to one another and
twisting of said foot relative to the leg of the user.
2. The structure of claim 1 wherein the means swivelly
mounting said leg support on the rearward portion of said
foot support comprises a ball and socket joint and wherein
means are provided for holding said supports in a selected
position relative to one another.
3. The `structure of claim 1 wherein each -foot restrain~
ing block includes a T-shaped slot on the undersurface

The brace shown and described herein is easily used Yfor
many corrective situations. For example, it may be used
to correct the disposition of the plane of the lfoot relative 20 thereof and extending laterally thereof, said foot support
to the lower leg by twisting the foot support 10 upwardly
or downwardly with relation to the leg support 24 and then

may be used to twist the general plane of the foot relative
including spaced sl-ots extending generally radially from
said leg support, a bolt passed through each slot on said
support, and a nut threaded on said bolt and in sliding
engagement with each T-shaped slot, so as to tix each
