Tip

Shoe size table

If you really want to be precise, you

could go to a shoe store on a quiet day

and measure the length and breadth

of different sizes of shoe. A table

showing the length and width of the

soles along with the matching shoe

sizes will make your work easier on

later assignments. You can also use

the “footprint length (in cm) minus

two centimeters times seven” rule of

thumb to determine the approximate

height (in centimeters) corresponding

to the shoe size, and then write this

into your table as well. Remember, this

is just an approximation.

Measuring tracks and prints

You will need:

Measuring tape (centimeters)

Slide gauge (from die-cut sheet)

Glue stick

Paper

Pencil

Soft ground, sandbox if necessary

Here’s how:

1. Assemble the slide gauge as

shown in the illustration on page

28. Be careful to read the right

measurement numbers on the

scale that goes with it. The different

colors will help you. Men’s, women’s,

and children’s shoe sizes are shown

in different colors. All of the shoe

sizes are approximations because

there are a lot of variations in shoe

sizes. Try measuring different kinds

of shoes at home or at a friend’s

house, and check how well the

length of the soles matches the

indicated shoe size.

2. Walk slowly across a sandy

surface, and then try running next

to where you walked. Which prints

are deeper? Did the stride length

change?

3. Repeat the experiment, but this

time try walking backwards. How do

the footprints look now?

4. Compare different footprints and

shoes. With a little experience, you

can learn to draw conclusions about

the kind of shoe from the kind of

print: high-heeled shoes, gym shoes,

soccer shoes, hiking shoes, rubber

boots, sandals, etc. The condition of

the pattern also reveals something

about the age of the shoes.
