How to measure your foot

Measure in the evening: feet get slightly larger during the day. Measure both feet and use the larger value.

  1. Get readyPlace a sheet of paper on a flat floor against a wall. Wear the socks you'll wear with the shoes.
  2. Stand straightPut your foot on the sheet with your heel against the wall and put your weight on it.
  3. Mark itHolding a pencil upright, mark the tip of your longest toe. Repeat for the other foot.
  4. MeasureMeasure from the edge of the sheet to the mark. Round to 0.1 cm and use the larger value.

Mistakefeet are smaller in the morning than in the evening

Do this insteadmeasure in the evening after a normal day

Old size

Mistakefeet change with age, weight and pregnancy

Do this insteadre-measure your feet once a year

One foot only

Mistakefeet often differ by a few millimetres

Do this insteadgo by the larger foot

No socks

Mistakea thick sock can take up half a size

Do this insteadmeasure in socks for that season

Brand A = brand B

Mistakeevery factory uses its own lasts

Do this insteadcheck the insole length on the product page

"They'll stretch"

Mistakeleather stretches a little in width, not in length

Do this insteadnever buy shoes that are short in length

Shoe sizes: encyclopedia entry

Shoe size

A shoe size is a conventional number that shows which foot length a shoe fits. Because shoes need room for the toes to move, the size depends not only on the foot but also on the length of the last the shoe is made on.

European system (EU)

The European, or French, system measures last length in Paris points. One Paris point equals 2/3 cm, about 6.67 mm, so neighbouring EU sizes differ by 6.67 mm. This is the system most shops in Ukraine and Europe use.

British and American systems (UK, US)

The British system counts sizes in barleycorns — units of 1/3 inch, about 8.47 mm. The American system uses the same step but a different starting point: US men's sizes are about 1 larger than UK, and US women's about 2 larger. That's why the same EU size corresponds to different US numbers for men and women.

Metric system (Mondopoint)

International standard ISO 9407 describes the Mondopoint system, where the size equals foot length in millimetres, sometimes together with width. It is used for ski boots and military footwear. The former Soviet metric system also gave size as foot length, but in centimetres.

Width

Besides length, shoes differ in width — the girth of the foot at its widest point. European makers mark it with letters or numbers, and product descriptions often say "wide fit" or "standard width". People with wide feet or a high instep should pay as much attention to width as to size.

Choosing a size online

The most accurate way to choose a size online is to compare your foot length with the insole length of the model. For closed shoes the insole is usually 0.5–1.5 cm longer than the foot: less room for summer shoes, more for winter shoes worn with warm socks.

Questions and answers

What if I'm between two sizes?

For closed and winter shoes, choose the larger size; for summer and open shoes, go by the insole length and fit.

Are sizes the same across brands?

No. Each factory uses different lasts, so one brand's size 39 can be longer or shorter than another's. The insole length on the product page is the most reliable guide.

How much room do I need?

Usually 0.5–1 cm for summer shoes and 1–1.5 cm for winter shoes, so your toes can move freely and your feet stay warm.

Can I exchange shoes if the size doesn't fit?

Yes. Shoes of proper quality that haven't been worn and are in their original condition can be exchanged within 14 days. Ask our consultant for details.

How do I choose if one foot is bigger?

Go by the larger foot. A few millimetres on the smaller foot are easy to make up with an insole.

Not sure about your size?

Send us your foot length and our consultant will find a model by insole length.
