Choosing the Correct Shoe

Anatomy of an Athletic Shoe

Upper

– The part of the shoe above the midsole that

wraps around and over the top of the foot.

– Nylon mesh

– Light weight

– Durable

– Water Resistant.

• Midsole (one of MOST IMPORTANT)– The cushioning layer of material between the

upper and the outsole

– 1st to wear out/minimal visual cues– 45% loss shock absorption after 500 miles midsole

– Compression molded EVA, polyurethane

or a combination of the two

– Shoes may offer air, gel, or some

other liquid

to increase the shoes cushioning ability. midsole

Anatomy of an Athletic Shoe Outsole

– Strikes the ground– Provides traction and durability– Carbon rubber and blown rubber are two common materials used– Typical designs include nubs, ripples, waffles, and flex grooves(which can increase flexibility and decrease weight).

7

Anatomy of an Athletic Shoe• Insole (sockliner)

– The soft removable liner that fits snugly into

the shoe above the midsole

• Heel counter

– A firm cup that is encased in the upper and

surrounds the heel

– This part controls rear foot motion

– Increases absorption on heel strike by 19%.

Anatomy of an Athletic Shoe Heel notch

– Slight depression on the heel of the upper– Function: heel notch

• Improves fit

• Prevents irritation along the

Achilles' tendon

• Tongue:– Should be well padded– Not interfere with flexion of foot.

– Secure across the midfoot Toe box:

– Provide sufficient room for toe clearance

– ½” RULE for upper and end.

– Straight:

• Best for flat feet

– Curved:• Best for high arched

• Best for normal feet.

Buying Shoes Things that should be considered before

buying a shoe– Type of foot

– Degree of pronation

– Type of arch

– Body weight

– Environmental considerations.

12

Types of shoes Cushioned

• Motion control

• Stability

• Trail

• Racing.

Types of Feet Floppy feet

This person would benefit from a motioncontrol shoe

Rigid feet This person would benefit from a cushionshoe so that they can avoid injuries

Normal feet This person can benefit from a properly stableand cushioned shoe.

21

Degrees of Movement• There are two types of movement the

foot makes in relation to running– Pronation

– Supination

• Pronation refers to the inward rotation of the

top of the foot after it makes contact with the

ground

• Supination refers to the outward rotation of

the foot as it “toes off.”

22

Overpronator The shoe will lean excessively inward

• Recommendations:– Firm, multi-density midsole

– External motion control device

– Straight or slightly curved shape.

23

Underpronator The shoe will lean excessively toward the

outside Recommendations:

– Highly cushioned

– Curved shape

– Slip lasted construction.

24

Normal Pronation The shoe will a have a generally straight

wear

• Recommendations:– Fairly easy to find a shoe that fits this foot.

27

Types of Arches It is also important to

understand the

different types of arches that a foot may

have a way of finding out what type of arch a

person has is the “wet test.”

28

Low Arch

“Wet test” reveals a full imprint

These people tend to overpronate as well

• Recommend:– A shoe with a more

straight shape.

29

High Arch

“Wet test” will reveal a very small footprint.

• These people tend to have a more rigid foot as well

• Recommend:– Midsole cushion

– Curved shape.

30

Normal Arch

“Wet test” will reveal normal

foot shape

• Recommend:– This person can wear a

variety of shoes from

slight to curved.

31

Environmental Considerations

Asphalt Surfaces

– Shoes with midsole shock absorption

– Outsole durability:• Carbon-rubber: last longer

• Blown rubber.

32


Tracks (all weather rubberized)– Can get by with less cushioning

than when running on asphalt or concrete

– Need more motion control due to the turns that you encounter while on a track.

33


Trail– Same as track for cushioning– Should look for a shoe with more

all around support– Should offer a more durable

upper and outsole– Typically have a more off-road

traction sole– Many trail specific shoes tend to

be heavier than their road counterparts

34

Purchase Tips Most important thing is:

– FIT!!!!! It has to fit properly to work properly

Expect to pay $40-$110 for a good pair of shoes• Look for shoes later in the day when your feet

are at their widest and longest If you wear orthotics bring them with you when

trying shoes on Try and wear the socks that you typically run in

with you when trying on shoes

35

Purchase Tips Buy a shoe that is going to meet your

training needs Know what type of foot you have so you

can narrow your choices down The “coolest” looking shoe Lie them on flat surface

36

Purchase Tips Try both shoes on to ensure proper fit of:

– Width

– Length

– Heel cup

• “Breaking In” shoes?

• First run on treadmill.

37

Shoe Care Wear your running shoes exclusively for

running. Don’t "kick-off" your shoes by scraping the

heel off of one foot with the toes of the

other. This may lead to early "breakdown"

of the heel counter.

38

Shoe Care Follow the cleaning instructions as provided

by the manufacturer. If no instructions are provided, consider the following tips:- Do not machine wash, dry clean or tumble

dry your shoes.

- Wash them using a soft brush, mild detergent and water. Allow them to air dry.

39

Shoe Care Intense heat exposure for extended periods

of time breaks down the outsole

Wet shoes will significantly lower the

shock absorption of the shoe.

40

Shoe Replacement Every 6 to 9 months

• Every 400 to 600 miles

• Fig 1 shoes are 9 months old with 400

miles

• Fig 2 shoes are 18 months old!

42

Thank You for Your Attention Good Luck and it’s great to

see everyone running and helping people at the same time.
