1. Instep

The instep covers the top of your foot – all our boots have zips that come down to the very bottom of the boot, this will make it easier to get your foot into the boot if you have high insteps. If the boots are too tight try a size up.

2. Toe

At DuoBoots we offer a few different styles of toe shape – rounded, almond, and pointed – if you are in-between sizes and want a more pointed toe it may be more comfortable to size up. Reach out to our customer service team who will be able to assist you further.

3. Shaft

The most important part of our knee high boots! We measure the shaft from the top of the heel to the very top of the boot. The shaft is where we do the majority of our customisations – depending on the style, they will come in one or three different heights, but every style has our signature eight different calf sizes. Read more on our sizing pages.

4. Foot Width

All our boots have a medium width around the ball of the foot – find the exact measurement in our handy size guide. (Click on the Boot Sizing tab above)

DuoBoots aren’t your average pair of boots! Each style comes in 72 different size combinations – incorporating foot size as well as calf size - so we understand that finding the perfect fit can be more complex than your average shoe shop.

Our shoe fit uses standard sizing – so go for whatever shoe size you normally go for. For pointed-toe boots such as the Freya or the Saffron and heeled boots such as the Belmore we suggest sizing up in the foot.

We understand that every foot is different. All our sizing is based on standard international measurements - however if you are unsure on sizing, it is always best to check.

Using our foot measurement chart above - check the length of your foot from the top point of your foot right to the back of the heel.

For the width measure from the base of the big toe to the base of the little toe - this will go diagonally down across your foot - rather than straight across!
