Are you wondering, "Do UGGs run big or small?" You’re not alone. Many people find it tricky to get the right size. The last thing you want is to spend your hard-earned money on boots that don't fit well. But don’t worry.
We’ve got you covered.
UGGs run large, especially their classic boot styles. That’s why many customers recommend sizing down. In our opinion, the sheepskin lining compresses and molds to your feet over time. So, for a snug fit, choosing a size smaller than your usual is advisable.
In this guide, we’ll share everything you need to know to find your perfect UGG fit. Stick around, because these tips will save you time, money, and a lot of hassle!
Key Points
- UGGs typically run big, so sizing down is often necessary.
- Your foot shape affects how UGGs fit. If your feet are wide, UGGs may fit perfectly.
- Different UGG styles fit differently, with some being more roomy than others.
- We suggest walking around in UGGs before buying (to ensure they fit comfortably).
- UGGs will stretch over time, so start with a snug fit.
Do UGGs run big or small? Find Out the Details
UGGs generally run big. Most people find that UGG boots have a roomy fit, which means they may feel larger than other shoes. If you're thinking about buying a pair, you might need to size down. We highly suggest this to those who prefer a snug fit.
Let’s break down the reasons why they feel a bit larger than other shoes.
The Sheepskin Material
UGGs are made from high-quality sheepskin, which is soft and stretchy. In our experience, sheepskin expands and molds to the foot shape as you wear it. This means that even if your UGGs feel snug at first, they’re going to stretch out over time.
We’ve seen this happen time and time again.
After a few wears, UGGs become roomier. That’s the main reason why they run big.
The Plush Wool Lining
Another reason UGGs run big is the plush wool lining (inside). In our experience, the wool is thick and fluffy when the boots are new. We’ve also noted that it takes up a lot of space inside the boot.
However, as you wear them, this wool flattens out.
In our opinion, this is one of the main reasons people feel like their UGGs have gotten bigger over time.
The Roomy Design
Did you know UGGs are designed to be roomy? Yes, they are. This isn’t a mistake - it’s intentional. The brand designs these boots with extra space to ensure that they’re:
- Comfortable
- Warm
- Easy to wear.
We think this extra room is what makes UGGs so popular.
The roomy design is especially noticeable in the toe area. UGGs usually have a rounder, more spacious toe box, which gives your toes plenty of room.
We’ve tested this ourselves, and we can tell you that this extra space is one of the reasons why UGGs are so comfortable.

Key Factors That Influence UGG Fit
UGG fit is influenced by many factors, which are:
- Your foot shape
- The style of the UGGs
- How you wear them.
Let’s read the details.
The Style of the UGGs
Mark our words: The style of the boot can make a big difference. Let’s take two examples:
- The classic UGG boots usually have a more relaxed, roomy fit.
- But if you go for something like the UGG Classic Slim, you’ll find it fits closer to your foot.
That’s not it. The height of the boot matters too. We’ve found that a tall UGG fits differently around your calves compared to a shorter or mini style.
So, the style you choose will affect how UGGs feel on your feet.
How You Wear Them
How you plan to wear your UGGs also changes the fit. If you like to wear them barefoot, you’ll probably find them feel roomier (as compared to wearing them with thick socks).
Plus, if you want to wear your UGGs regularly, the material will stretch out more quickly. Keep this in mind when you’re deciding on your size.
Your Foot Shape
The shape of your feet has a lot to do with how UGGs will fit. If you’ve got wider feet, you will find that UGGs feel a bit tighter on the sides.
But if you have narrow feet, you may notice some extra space inside the boots.
That’s why we suggest measuring your feet before buying UGGs. After this, match the measurements with the charts the brand has published on the internet.
Don’t worry. We’ve got them.
