• Feet bear the full weight of the
body and as such are the
foundation of the body
• On average a person can take up to
18,000 steps per day
• A 70 year old person will have
walked in their lifetime, an average
distance equivalent to walking
around the world 3 times
Foot AnatomyFoot Anatomy
The skeleton of the foot is
made up of 26 bones.
TARSUS – heel of the foot
•Consists of 7 irregularly
shaped bones at the back of
the foot
METATARSUS – middle
of the foot
•Consists of 5 long bones
along the middle of the
foot.
PHALANGES – toes
•Consists of 14 short
bones that form the toes

1. The main joints of the foot are:
2. Ankle Joint – a hinge joint
3. Sub Taler – a gliding joint
4. Mid Tarsal – a gliding & ball-and-socket
joint
5. The skeleton of the foot is held together
by:
6. 109 ligaments
7. 32 Muscles and tendons (for movement)
Types of FeetTypes of Feet
• ECTOMORPHIC – Long and thin
• MESOMORPHIC – Muscular and heavy boned
• ENDOMORPHIC – Small bones and fleshy

While Weight Bearing
• The foot becomes longer
• It also becomes wider across the
ball.
• The heel becomes wider and
arch lower
On an average foot increase by
approx. 5% (in volume) by the
night. The percentage can
increase in warm weather and
decrease in cold weather
Measuring Foot size
Measuring Foot sizeMeasuring Foot size
Standing
1. Measure both feet
2. Measure the longest toe
3. Always measure the foot
size from the foot not
from the shoe
Measuring Foot sizeMeasuring Foot size
Sitting
1. The foot must be correctly positioned in the
foot gauge
2. The stool must be in line with the leg
3. The heel must be right back to the pillar

1. For what activity will the
shoe be worn ?
2. Where will the shoe be
worn ?
3. Any extreme variations in
temperature?
4. How long will the customer
wear the shoe at a stretch?
5. Style Preference ?
Shoe Fitting PointersShoe Fitting Pointers
• Measure both feet. No two feet are
the same size. Fit shoes for the
larger foot
• Ask customer to wiggle toes in the
shoes. If he/ she can’t, the shoes are
probably too small. 3/8" to 1/2" of
space between your longest toe and
the end of the shoe is recommended
Shoe Fitting PointersShoe Fitting Pointers
• Ask the customer to walk around
the store to ensure a comfortable fit
before buying
• Ask the customer to walk on
different floor surfaces (available in
store) prior to buying
• Provide customer with socks to try
on shoes with which he/ she will
wear them

DISORDER CAUSE SUGGESTION
Blister
a bubble on the skin filled with fluid Caused by friction in socks or shoes that are loose
and slip around
Correct sizing of the shoe
Corn
hard thickening of the skin that has a central core
where pressure is severe
Excess pressure or friction usually due to footwear
that is too tight
Correct sizing of the shoe
Bunion
inflammation and swelling on the side of a joint Prolonged compression of the toes in a short shoe Shoes that come in various width sizes
Ingrown Toenail
toenail grows into the skin and flesh Pressure on the nails from crowding of toes or too
short shoes or hosiery
Correct sizing of the shoe
Hammer Toe
joint of the toe is permanently bent downward Shoe too short or narrow pointed shoes Correct sizing of the shoe
High In-step or High Arch Congenital Tendency Very good arch support or motion
control athletic shoes

2. Assess if ‘age’/ wear and tear
is due to
– FIT
– SHOE
1. If yes, inform the customer of the shoe wear
and tear due to appropriate fit/ shoe
2. Recommend a more appropriate fit or shoe
to the customer
Worn Shoe EvaluationWorn Shoe Evaluation
1. Wear on the sole should be even
2. If the wear is forward, then the shoe is too
short
3. If the shoe is worn on the outside edge or
the inside, then the shoe is too narrow or the
person leans outwards or inwards
4. If the toe of the shoe is turning up then the
shoe is too long

1. Normally the vamp will not develop
excessive wrinkles or creases, nor it will
have pronounced indications of each of the
toes
2. A shoe that is too wide will develop large
creases or folds across the vamp
3. A shoe that has toes impressions on vamp is
too short or too narrow, or made on the last
which isn’t appropriate

• Ball Width and Vamp Room
– Adequate space across the vamp of
the shoe
– Width of the insole same as the width
of the foot.
• Heel Fit
– Not too tight or too loose, “snug” fit.
– Top of counter does not “cut into”
heel tendon
– Inside and outside ankle bones do not
rub against top line of shoe.
Fig: Right heel in shoe. The slight
offset between the axis of the leg
and the axis of the shoe puts
stress on the shoe counter, hence
the need for a firm and
substantial shoe counter.

• Top Line
– Fits snugly to sides of the foot.
• Instep of Waist
– With slip-ons it is important that
the shoes are not too tight and not
too loose but must be snug enough
to hold the foot.
– With laced shoe it is possible to
adjust the fit over the instep
