Select a shoe or foot size in the drop down menu for the size scale you want to convert from.
The other drop down menus will show the equivalent shoe and foot sizes in their respective size scales.
Shoe Size Issues
Shoe sizing is not standardised throughout the world, or even within specific countries.
There are often physical size differences between similarly sized shoes from different manufacturers.
This is due to the various methods used to measure shoes, and to various manufacturing methods.
Actual shoe sizes may differ between identically sized shoes made in different countries,
even when both countries use the same sizing scale.
For example, a "Spanish" size 41 shoe may be physically larger or smaller than an "Italian" size 41,
yet both countries use the European sizing scale.
Advice for Shoe Buyers
Try Before You Buy
Always try a pair of shoes before you buy them, even when the shoe is "your" size.
If you are buying shoes by Internet or mail order, check the seller's return policy.
You may have to return shoes that you bought by Internet or mail order if they do not fit properly.
Buying Shoes by Internet or Mail Order
Measure both feet heel to toe in millimeters or inches.
You will likely find that one of your feet is larger than the other. This is normal for most people.
Using this converter find the shoe size of your largest foot. Order shoes sized to your largest foot.
Ask the seller if you can return shoes that do not fit, and ask if they charge a fee on returns.
Most likely you will have to pay return postage when you send shoes back to the seller.
How Shoes are Measured
Shoe size can refer to one of three lengths.
The length of the foot that fits the shoe
The length of the inner cavity of the shoe
The length of the "Last"
Defining shoe size on the length of the human foot is inconvenient for manufacturers and is seldom used.
It forces manufacturers to test new shoe designs in order to be certain that their
shoes will fit properly on feet of different sizes.
Inner Cavity Size
Defining shoe size by this method is more convenient for shoe manufacturers, because it is easy
to measure the size of the inner cavity of a finished shoe, but is subject to inaccuracy
due to manufacturing tolerances. In a shoe of the correct size, the inner cavity is
typically 15 to 20 millimeters longer than the foot.
Size of the "Last""Last" is an object that is shaped like a foot, on which a shoe is built.
The size of the "Last" is the most convenient method for manufacturers
to define the size of their shoes, because it is easy to measure the size of a "Last",
and because this method does not make any promises about how a shoe will fit a particular foot.
This is the most common method used to define the size of a shoe.
