30
Q

what characteristic would an in-depth last produce in a shoe

31
Q

when would an in-depth last be indicated (4)

A

  2. to accommodate dressings
  3. when there is increased edema in the foot
  4. severe deformities in the foot
32
Q

when may a custom molded shoe be warranted

A

when there is a significant deformity in the foot which could not be accommodated in an extra depth shoe with inserts

33
Q

key ares to identify for shoe fitting (3)

A

34
Q

guideline for shoe length

shoe length should be 1/2 inch longer than the longest toe

35
Q

the widest part of the shoe should be aligned with…

A

the 1st metatarsal phalangeal joint

36
Q

how to measure depth in shoe fitting

A

examine the fit of the vamp and toebox for adequate clearance

37
Q

what position should fit be evaluated in

A

in a weightbearing position (because the foot spreads when it’s open) and non-weightbearing position if there is a flexible deformity

38
Q

what else may be considered that may influence size of the foot (2)

A
  1. time of day

2. prior activity level

39
Q

at the end of the day or after exercise, the foot can experience a ___ shoe size increase

A

1 - 1.5 shoe size increase

40
Q

a lift is primarily used to…

A

accommodate for a leg length discrepancy

41
Q

when else may a lift be used

A

to promote greater ease in swing on the contralateral side

42
Q

how much of a life can be accommodated within a shoe

A

approximately 1/2 inch

43
Q

what is the function of a cushioned heel

Q

when is a cushioned heel indicated

A

when there is heel pain and may also be prescribed when the individual is using a solid AFO to assist with forward weight shift

45
Q

the overall function of a rocker sole, metatarsal bar, and rocker bar?

A

to promote smooth transition from heel strike to push off while relieving stress from the metatarsal heads

46
Q

what is a rocker sole

A

extends the length of the sole of the shoe

47
Q

what is a metatarsal bar

A

a strip of leather or rubber placed just posterior to the metatarsal heads

48
Q

what do the rocker styles do

A

serve to reduce stress at the metatarsal heads during pushoff phase of gait

Q

when are the rockers indicated

A

whenever there is pain in the metatarsal heads

increases the medial-lateral surface area on the bottom of the shoe

Q

where can a flare be placed

A

medial or lateral

52

increase individual’s BOS when they are wearing shoes and may prevent inversion/eversion injuries

61
Q

function of a wedge

A

help correct flexible deformities or support rigid deformities

62
Q

what is a Thomas Heel

A

an extension of the breast of the heel anteriorly on medial side

63
Q

what does a Thomas Heel do

A

increases stability of the sole of the shoe when there is pronation

64
Q

what is a Reverse Thomas Heel

A

the breast of the heel is extended anteriorly on the lateral side

65
Q
