Empire Footwear Size Guide

Sizes preceded by a W are women’s sizing. This means that a size displayed as W09 is a women’s size 9. There are some models made for both men and women, in which case both sizings will be displayed one after the other. This means that the Unisex(Men) sizing will be displayed first, followed by the women’s sizing. (Ex: 07.5/W09, this sizing would designate a size 7.5 for men and a size 9 for women.

Sizings preceded by a K will designate Kids’ sizings. (Ex: K03 will be a size 3 for kids) Sizings preceded by a T will designate Toddlers’ sizings. Sizings preceded by a B will be Baby sizings.

If you’re unsure about a sizing feel free to reach out to us!

Les grandeurs qui sont précédées d'un W sont des grandeurs pour femmes. Ceci veut dire qu'un W09 équivaut à un 9 de femmes. Il peut arriver que certains modèles s'adressent aux hommes et aux femmes, auquel cas nous montrerons les deux grandeurs une à la suite de l'autre, c'est à dire la grandeur Unisex(homme) en premier suivie de son équivalent en grandeur femme. (Ex: 07.5/W09, cette grandeur équivaut à un 7.5 d'homme ou un 9 de femme.

Les grandeurs précédées d'un K sont des grandeurs pour enfants (KIDS) (ex: K03 équivaut à une grandeur 3 d'enfants). Les grandeurs précédées d'un T sont des grandeurs pour tout-petits (TODDLER). Les grandeurs précédées d'un B sont des grandeurs pour bébés.

How To Measure - Clothing

Follow these easy steps to get the right size. For the best fit, measure your feet at the end of the day.

Step on а piece of paper with your heel slightly touching a wall behind.
Мark the end of your longest toe on the paper (you might need a friend to help you) and measure from the wall to the marking.
Do the same for the other foot and compare measurements with our size chart to get the right size.
