cork and latex
used a great deal in accommodative device
easy to work with and to grind
accommodative device made from leather and korex, “leather rubber butlers”
korex
name this soft material

can create insole and have patient wear for a week or two
easily heat moldable
available in different densities
plastazote
name this soft material
many different types of sponge related materials
PPT, poron, pelite
good for shock absorption
again available in different densities
can be used in any instance where more shock absorption is required
used in arch area of rigid orthotics to provide greater strength
sponge
name this top cover
neoprene with a fabric cover that dispenses shearing forces
provides shock absorption plus decreases shearing forces
good for athletes
helps to decrease callus formation and blister formation during increased activity
fabric cover will separate
spenco
name this top cover
cowhide
used in accommodative devices
strong, long lasting top cover
problem it absorbs sweat and gets ripe
treated to prevent the above
leather
name this top cover
