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 http://www.google.com/url?sa=i&rct=j&q=shoe+last&source=images&cd=&docid=q5Kd0s2ZGezjNM&tbnid=teUim7327_HEeM:&ved=&url=http%3A%2F%2Fwww.rei.com%2Flearn%2Fexpert-advice%2Frunning-shoes.html&ei=6ROQUf3PDo2diAej3oHIAg&bvm=bv.46340616,d.aGc&psig=AFQjCNGDBlmGh1m44AMHQwlZVPZJxMJsiw&ust=1368483177593564
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 http://www.google.com/url?sa=i&rct=j&q=heel+counter+test&source=images&cd=&docid=KfcuIwAVZZ5jXM&tbnid=opt2ihPlJqjgXM:&ved=0CAUQjRw&url=http%3A%2F%2Fwww.therunnershigh.com%2Farticles%2Fdefrunningasa2.html&ei=uB2QUbODHq-ViQfX5YGIAg&bvm=bv.46340616,d.aGc&psig=AFQjCNHb0cKBVixwjuyMOQr7H3q6ATnLfQ&ust=1368485644751002 http://www.google.com/url?sa=i&rct=j&q=heel+counter+test&source=images&cd=&docid=SROGfnHg03Rs-M&tbnid=VLcW9nn0zKj2HM:&ved=&url=http%3A%2F%2Fwww.footankle.com%2Fshoes.htm&ei=jB2QUfPZGIePiAe3joHoBw&bvm=bv.46340616,d.aGc&psig=AFQjCNHb0cKBVixwjuyMOQr7H3q6ATnLfQ&ust=1368485644751002 Adapted for Arnold Ross, DPM

Shoe recommendations • APMA • AAPSM • You don’t need to recommend a manufacturer, but give patients the knowledge to find their own 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 http://www.google.com/url?sa=i&rct=j&q=diabetic+shoe+display&source=images&cd=&cad=rja&docid=G3f3-iK-Qg-NPM&tbnid=Y8ltNc5-6F4p3M:&ved=0CAUQjRw&url=http%3A%2F%2Fwww.freemandrug.com%2Fid64.html&ei=cCSRUfiWH82ViAeV3YGgBA&bvm=bv.46340616,d.aGc&psig=AFQjCNF_wkPftLE5ldCZiUBxAVm3rINALg&ust=1368552931325909
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
