Heel pad

A
  • for shoe fitting purposes, indicated for malleolar irritation from the topline
  • may also be used when the heel counter is too rigid and too concave

Q

lateral heel flare forces

A
  • early pronation at heel strike

- prevents lateral roll-over (excessive RF inversion) in midstance

18
Q

medial heel flare

A
  • decelerates pronation in midstance

- helps prevent the foot from rolling over (in the direction of pronation)

19
Q

Stabilizers

A
  • act to increase the base of support
  • helps reinforce the upper in terms of the shoe’s ability to prevent the foot from rolling over the shoe
  • extends from the sole to about 1/2 way up the upper of the shoe
20
Q

Stabilizers are also known as

A

flanges or buttresses

21
Q

Medial Stabilizer

A

-indicated for pronatory problems such as posterior tibial tendon dysfunction and severe flexible flatfoot

22
Q

Lateral heel stabilizer

A
  • indicated for lateral instability such as severe RF varus such as found with residual clubfoot
  • may also be used for pts who demonstrate excessive lateral shoe wear
23
Q

Rockers

A
  • sole modifications that allow the shoe to take some of the motion less motion is required by the foot/LE
  • angle and base of gait must be taken into account
24
Q

heel rockers allow for

A

-a more controlled loading at heel contact

25
heel rockers are useful in pts with
-decreased ankle joint motion
26
heel rockers are required for
very rigid soled shoes (to prevent Frankenstein gait)
27
FF Rockers decreases or eliminates the need for
MTP motion
28
FF Rocker indicated for such conditions as
hallux limitus/rigidus, MTPJ arthritis, painful plantar MT head hyperkeratoses
29
Toe Rockers provides for
- toe-off | - important for rigid soled shoes
30
double rockers help to
offload the midfoot
31
Heel to Toe Rocker used for
very rigid foot/ankle | -do not use bilaterally!
32
MT bars used to
- off load the MT head | - decrease motion requirements at MTPS
33
MT bars are not good for pts with
neuropathy, drop foot
34
Excavations
-the sole of the shoe may be "excavated" ( a hole is cut into it) either internally or through the outsole to help off-load an area
35
Excavations can be used to
off load bony prominences, ulcers, areas of severe hyperkeratoses
36
Sole Expansions
- widens the sole of the shoe - may be used for HAV, tailor's bunions or midfoot deformity (such as mild midfoot, collapse in Charcot neuroarthropathy)
37
Closures may be used for
- unable to reach feet (ie. back problems, obesity) - unable to manipulate hands (ie. severe rheumatoid arthritis effecting the hands) - significant and or changing edema
38
Velcro closure provides for
-god support and adjustability for those who have difficult with laces but can reach their feet
39
Elastic laces allow for
changing edema, may be used for patients with difficult reaching their feet
40
Side or Back closure may be used for
-patients who have difficult reaching their feet
41
custom molded shoes used for
- Charcot foot - stage 3 PTTD with rigid, severe abduction of the FF on the RF - severe congenital deformity - Rheumatod Arthritis with significantly deformity - Status post partial foot amputation with shoe filter required
42
custom molded shoes made from
- casts of pt's feet - cast must go above the ankle - may be b-vavle (most difficult but easiest to remove) - univalve - STS socks
43
Custom Molded shoes
- have a very rigid sole (some sort of rocker is required) - covered by medicare as part of the Therapeutic Shoe Bill (only for pts with diabetes who meet the specific requirements)
