shoes Flashcards
components of a good shode
minimizes stress on all portions of feet
provides support
shock absorber of GRF
role of sole
protects plantar surface from irregularities in surface
discuss parts of sole
welt - inside piece of outsole
insole - next to foot
outsole - most external
shank - bet heel and ball of shoe; prevents collapse and extra support
discuss soles of athletic shoes
rubber to provide traction and shock absorption
minimizes heel impact forces
discuss parts of the upper
vamp - from insole forward
tongue - extension of vamp in blucher but sep in oxford
rear quarter - joined to vamp o make sides and back of the upper
oxford shoe
outside quarter is cut lower to avoid contact c malleoli
bal-type oxford
back edges of vamp cover edges of quarter
blucher style
forward edges of quarter is on top of vamp
type of shoe closure for pt c orthoses and foot deformity
blucher
for pts c rigid ankle orthoses, fixed deformity or fragile neuropathic feet
lace-to-toe style
role of heel
beneath outer sole in anatomic heel
usually rubber, plastic or wood
role of heel counter
reinforces the quarters to help secure the shoe to the anatomic heel - pangit = paltos
aids in controlling rear foot
role of medial counter
helps support medial arch
role of toe box
at distal vamp
shields the toes and prevents anterior vamp to lose shape
role of lasts
model of the foot - wood, plaster or plastic
conventional last
forefoot slightly lateral to midlne
straight last
symmetric around midline
inflared last
directs forefoot medially
outflared last
directs forefoot laterally
keystone of a good shoe
absorb shock
relate heel height to the foot
can create stress on forefoot during gait
what is a molded insole
contributes sto foot stab, shock absorption and transfer of shear forces away from problem area
how is shoe size determined
by arch length not overall foot length
shoe mod for leg-length discrepancy
if 3/8 of an inch or more - full length external lift
if less than 3/8 of an inch - orthotic heel wedge inside shoe
indications for medial heel wedge
flexible valgus of calcaneus
indications for lateral heel wedge
flexible varus of calcaneus
indications for medial sole wedge
inverts forefoot
indications for lateral sole wedge
everts forefoot
indications for barton wedge
supports navicular and helps invert the calcaneus
shifts BW laterally
indications for metatarsal bar
prevents undue pressure on MTT heads during push off
indications for rocker sole or extended crepe rocker bar
redistributes BW over plantar surface for smoother and normal gait s stress and trauma to forefoot
shoe mod for AFOs
U-shaped orthotic bracket attached to shoe via 3 copper rivets
one on heel and 2 on shank
indications for medial thomas heel
prevents eversion
indications for lateral thomas heel
prevents inversion
shoe mod for metatarsalgia
wide width to reduce pressure on transverse arch
long fitting para di naka pflex MTP
cushion soles para mas ok absorption
high toe box to allow forefoot flexion and ext
shoe mod for morton syndrome
long medial counter for rearfoot support and stab
straight or flared last to accomodate foot shape
high wide to box to reduce compression in transverse arch
large enough to accomodate long 2nd toe
medial thomas heel or wedge to support medial arch
shoe mod for interdigital neuroma
shoe should be wide enough to eleminate transverse compression
enough length to reduce pflex of MTP
longe medial counter to prevent pronation
cushioned sole and low heel
shoe mod for plantar fascitis
long medial counter to limit heel valgus
high heel ro reduce tension on plantar fascia and achilles
adequate length to minmize compression and promote supiantion in toe off
shoe mod for pes planus fascitis
long medial heel counter
medial thomas heel or wedge
straight last
