Shoe Modifications Flashcards
Internal Shoe Modifications
Heel Grip Tongue Pad Metatarsal Raise FF Extension Valgus/Varus Wedges Heel Pad
when are internal shoe modifications used
shoe modifications are primarily used for improving shoe fit rather than treatment of a condition
Heel Grip
-wraps around the inside of the shoe
why should heel grips be avoided
- forces the foot into the toebox
- instead the grip should be cut in half and placed it on either side of the shoe to prevent from pushing the foot forward
is heel slippage normal
yes, a little bit is
Tongue Pad
- a better choice for heel slipping
- also used to help relieve irritation on the dorsum of the foot
Metatarsal Raise used
- directly on the foot
- as an orthotic modification
- as a shoe modification
MT raise used for pathology such as
- neuroma
- hyperkeratoses sub 2-4 MT heads
- pain sub 2-4 MT heads
MT raise used for shoe fit when pt has
shallow feet
FF extension used for
a shallow foot, too deep of a toebox
Valgus/Varus wedge used for
- may help with shoe fit
- not always a good idea b/c pushes the foot medially
valgus heel lift can prevent
pronation is some ppl
Heel pad
- 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
External Shoe Modifications
Flares Stabilizers Rockers Bars Excavations Sole expansions Closures
External Shoe Modifications
- may be used as a single therapeutic modality or in conjunction other modalities such as foot orthoses
- often reserved for more severe pathology or deformities
Flares
- may be heel or full length of device
- usually heel flares
- increases the base of support
lateral heel flare forces
- early pronation at heel strike
- prevents lateral roll-over (excessive RF inversion) in midstance
medial heel flare
- decelerates pronation in midstance
- helps prevent the foot from rolling over (in the direction of pronation)
Stabilizers
- 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
Stabilizers are also known as
flanges or buttresses
Medial Stabilizer
-indicated for pronatory problems such as posterior tibial tendon dysfunction and severe flexible flatfoot
Lateral heel stabilizer
- 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
Rockers
- 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
heel rockers allow for
-a more controlled loading at heel contact
