Tongue

• Prevents debris from entering• Protects against pressure of laces• Ensure it’s not too long to irritate leg

Padded collar

• Cushion• Achilles notch

Lower (sole) anatomy

• 3 components to the sole of a shoe– Inner sole– Middle sole– Outer sole

http://www.google.com/url?sa=i&rct=j&q=asics&source=images&cd=&docid=z06xqjP-ZYcpnM&tbnid=mcejDICpLGKXAM:&ved=0CAUQjRw&url=http%3A%2F%2Fhypebeast.com%2F2009%2F11%2Fasics-gtii-tweed-collection%3F_locale%3Den&ei=FyORUfW9DIS0iQf7wYHYDQ&bvm=bv.46340616,d.aGc&psig=AFQjCNEK5VoPanPLsFR_jt22pcfqHwf4KQ&ust=1368552560839283

Outer sole

• Portion of the sole that makes contact with the ground

• Provides traction, resists wear, and absorbs shock

• Treaded layer glued to midsole• Thinner than the midsole• Typically, either made from:– Blown rubber lighter, but less durable– Carbon rubber heavier, but more durable– Combination

Middle sole

• Thickest layer• Provides the majority of cushioning and shock

absorption• Modification layer• Typically made from EVA or PU– Ethylene vinyl acetate lighter, better cushioning,

deteriorates quicker– Polyurethane denser, heavier, more durable

Modification layer

• Mid sole cushioning devices• Medial post• Shank

Mid sole cushioning device

• Majority comes from EVA• Manufactures also insert their proprietary

cushioning systems (w/n midsole)• Most common cushioning systems use

encapsulated air, gel or other materials

Medial post

• Within the midsole (firmer) • EVA, thermoplastic

urethane, carbon fiber or other materials

• In stability and motion control shoes

• Not in cushioned or neutral shoes

• Size ,shape, & density determine amount of stability provided

Shank

• Stiffens the shoe under the arch

• Makes the middle portion of the shoe more resistant to torsion and flexion

• In most running shoes except the lightest and most flexible

• Assists shoe in bending at toes

• Adds weight

Inner sole

• Not visible on constructed shoe

• Junction attachment of the sole to the upper shoe

• Not an insert

Sizing

• Use a similar weight sock and orthotics• Leave at least ¼ inch (up to ½ inch) between

longest toe and end of shoe • Heel counter should be snug enough to

prevent heel from sliding• Fit shoe during the end of the day (swelling)• Shoes should never need breaking in• Always try on both shoes

Last

Shoe life

• Less dependant on age of shoe• More dependant on amount of usage and

signs of wear• Athletes vs non-athletes• Work vs casual• Differences among body habitus• Presence deformities

Shoe breakdown

• Occurs most commonly at the outer sole• Has has outer sole worn through to the middle

sole?• Is there a 4mm difference from the other side

of the heel?

Shoe breakdown

• Lack of middle sole shock absorption• Uneven on flat surfaces • Noticeable creases• General rule of thumb: Replace 300-500 miles

Shoe breakdown

• Heel counter deviation

Guidelines for replacement

• Even without use shoes can wear out• Depending on environment • Best to replace athletic shoes that are over a

year old• Can be expensive in short term• Will prevent injuries and keep patients active

in long run

Picking shoes

• Right shoe for the right foot• Best shoe for the job• Comfort & Function > Appearance• Remove/Avoid if irritating

Evaluating

• Straight heel• Counter test• Stable sole bottom• Bend at the toes• Torsion test

Shoe recommendations

• APMA• AAPSM

• You don’t need to recommend a manufacturer, but give patients the knowledge to find their own shoes

Minimalist shoes

Minimalist shoes

• Became popular after an article in Time in 2007• Predominantly anecdotal • Concept:– Feet were not meant to wear shoes, therefore,

cannot function efficiently with use– Barefoot/minimalist shoes allow strengthening of

the pedal musculature

Minimalist shoes

• Conflicting research• Difficult to assess• Assumes no deformity

Diabetic shoes

• AKA extra-depth shoes• AKA therapeutic shoes• Prescribed

http://www.google.com/url?sa=i&rct=j&q=diabetic+shoes&source=images&cd=&docid=uJEbQucQ4S-k7M&tbnid=aC64w_qbQqhp3M:&ved=&url=http%3A%2F%2Fwww.wcbl.com%2Forthotics-2%2Fdiabetec-shoes%2F&ei=4ziQUfmGJqKbigfr84Eo&bvm=bv.46340616,d.aGc&psig=AFQjCNFL-1QBiFX9KRnO7EKvDUiWbwc-mA&ust=1368492643971323

Diabetic shoes

• Function– Protect residual foot– Maintain position inside the shoe & reduce shear– Contribute to restoring normal gait– Allow for accommodation of orthotic device– Allows for modification e.g. steel shank or

rockerbottom

Diabetic shoes

• Supplied by orthotist or sale in private office

• Medicare supply new pair & 3 inserts each year

• Exam shoes during patient encounter

Conclusion

• Today’s shoes are variations of the 7 basic models

• Sole vs upper• Find the correct shoe for the correct foot for

the correct job• Diabetic shoes can help prevent ulcer

formation
