How to Choose Your UGG Size: A UK Guide

Getting the size right matters more with sheepskin footwear than with most shoes: a lining that feels snug on day one settles with wear, and a slip-on that is too long will never stay on properly. This guide explains how UK sizes convert, how to measure your feet at home and what to do if you are between sizes.

UK, EU and US sizes at a glance

All footwear at Moorvel is listed in UK women’s sizes, from UK 3 to UK 10, in whole sizes. As a guide, a UK 3 corresponds to an EU 36 and a US women’s 5, and each whole size up adds one EU size, one US size and roughly one centimetre of foot length. So a UK 5 is an EU 38 and a US 7, and a UK 7 is an EU 40 and a US 9.

The full conversion table is on our Size Guide.

How to measure your feet at home

1. Measure at the end of the day, when your feet are at their largest.
2. Place a sheet of paper against a wall and stand on it with your heel touching the wall.
3. Mark the paper at the tip of your longest toe, then measure from the wall to the mark in centimetres.
4. Repeat for the other foot and use the longer measurement.

Match that measurement to the foot length column in the size table. If you land exactly on a size, that is your starting point.

Classic boots: expect a snug first fit

Classic styles such as the Classic Mini II, Classic Ultra Mini and Classic Tall II are lined with sheepskin or a plush wool blend. The lining is thick when new and beds in over the first wears, so a boot that feels close-fitting at first usually ends up comfortable. For that reason, if you are between two sizes, the smaller one is usually the better choice for Classic boots. A pair that is loose from the start will only get looser.

Tasman and Tazz: stay true to size

Slip-on styles work differently. The Tasman II and Tazz II have a braided collar that does not stretch much, and because there is no back to hold your heel, your foot needs to fill the shoe properly. Choose your usual size. If you are between sizes or have wider feet, go up to the next size rather than down.

Winter boots, sandals and clogs

For winter and hiking boots, choose your usual size and allow room for the socks you plan to wear. For sandals and clogs, your heel should sit fully on the footbed without overhanging the edge.
