The only problem is these aren’t cheap. So, before you order yourself a pair online, it’s better to figure out the most important thing about sizing. Do UGG boots run big or small? In other words, are these boots true to size?

Do UGG Boots Run Big or Small? Are UGG Boots True to Size?

Do UGG Boots Run Big or Small?

UGG boots run big but that doesn’t mean they aren’t true to size. They’re somewhat in the middle. When trying out for the first time, these boots should feel snug without too much coziness. As the boots stretch over time, never settle for a larger size. 

Like every other leather boot, UGGs stretch a little bit after the break-in period is over. Thanks to your body weight and the leather’s elasticity, it takes the shape of your feet. It’s kind of like memory foam, but not quite.

Do UGG Boots Stretch? 

Like every other leather, sheepskin will stretch over time. But it won’t happen if you leave in a dark closet for too long. Then you’ll have to figure out how to get rid of mold from your UGGs

Genuine UGG boots are made from sheepskin which is designed to stretch half a size after the boots are broken in. This is why you shouldn’t settle for a bigger size even if they’re comfortable when you’re trying them out.

And if you ever wash those UGGs in a washing machine, those bigger boots will be even bigger than before. If you

It’s around day 14 to 15 when the sheepskin starts to mold to the shape of your feet. But if you somehow go for a size extra, the excess movement can result in painful blisters.

What you thought was cozy and comfortable won’t take much time to become a painful experience. But that doesn’t mean you should settle for smaller sizes too. 

Do UGGs Fit Wide Feet?

Classic UGG boots won’t have any problem fitting into wide feet. You don’t even have to size up. But that changes for their other styles, especially for the slim and tall styles. Although that problem might get resolved after the boots are broken in. 

Regardless of the style, all UGG boots are made out of leather. And like it or not, leather will stretch over time. As a matter of fact, sheepskin leather does it better by molding it to the shape of your feet. 

Even if you have a particularly hard time getting on the boots. Give it some time and see if it gets better. If not, you’ll know that size isn’t working for you.

Although if you’re quite sure you can work your way around it. Try stretching your UGG boots to see if that works.

How are UGGs Supposed to Fit?

A properly fitted UGG boot should give you a firm and snug feeling. Make sure your toes don’t curl up and your heel doesn’t slip when you walk. Avoid sizes that feel too cozy or comfortable. UGG boots are supposed to stretch half a size, meaning you shouldn’t size up. 

Think of UGG boots like denim jeans. Ever noticed how extremely firm jeans are when you first try them out? Well, it’s the same for UGG boots. 

What happens is, the wool gets compressed with your body weight while molding to the shape of your feet. At the same time, the suede exterior also stretches due to mechanical stress thanks to your foot movement. 

The bottom line? Never settle for boots that are TOO LOOSE.

How to Measure UGG Boot Size?

This is probably the easiest way to find out your shoe size. And it requires nothing but a piece of paper and a marker. Here’s how to do it- 

Step 1: Draw a Line on a Piece of Paper 

Take a piece of paper and put a straight line using a marker. It doesn’t have to be a marker, anything from a pen to a pencil works. 

Step 2: Stand on the Piece of Paper

Put the paper on a surface so that you get an accurate measurement of your feet. Next, stand on it with the straight line placed in the middle.

Step 3: Put Marks on Both Sides

Put a mark where your longest toe ends. On the other hand, place another mark where your heel ends. Repeat the same process with a different paper for the other foot. 

Step 4: Figure out the Distance to Find Your Shoe Size 

You already know what to do. So, let’s skip the explanation. 

However, what are you supposed to do if one foot is bigger than the other? In that case, always settle for the larger size. 

Do UGG Boots Come in Half Sizes?

UGG boots come in half sizes for the chukka, waterproof, and regular boots. The only exception is their classic UGG boots. Even if you need a half-size, you have to settle for a whole size. 

Although don’t stress over it. Sheepskin leather is known for its stretching abilities. That said, go for the closest size without sizing up. As the boots stretch over time, sizing up might lead to an uncomfortable wearing experience.

Can You Shrink UGG Boots?

‘’My UGGs are too big, what can I do?’’. Does this situation seem familiar to you? 

Apparently, this is a pretty common scenario for a lot of people. However, the problem is the only way to shrink leather is to dump it in hot water. Needless to say, I would never recommend you do that. 

The only solution you’ve got is to wear a thick sock. But even that ruins the purpose of wearing UGG boots. I mean, you are wearing these boots for the soft and furry inside. 

If it’s possible, try to change the size. Otherwise, your only option is to wear thick socks unless you want to face blisters.


Do You Wear Socks with UGGs?
Unless the boots are bigger for you, never wear socks with UGGs. These boots have a natural sheepskin interior. If you don’t know, remember this might be the most comfortable and cozy inside you’ll ever see. When you wear socks, they get in the way of leather fibers molding to the shape of your foot.

How Do You Reshape UGG Boots?
If you don’t want to lose the shape of your UGG boots, use the paper trick when you dry them. After washing the boots(try not to wash that frequently), stuff the boots with butcher paper or tissue paper. But avoid using newspapers as the ink might damage the interiors.

Why Are UGG Boots so Hard to Get on?
The overall design and comfort factor sometimes makes UGG boots a bit hard to put on. But instead of pulling the boots, use your body weight to slide your foot while the boots rest on the floor. Not all UGG boots come with pull tags. So, be as gentle as possible with your UGG boots. Remember, they are UGG boots, not Doc Martens.

How Can I Make My UGGs Break Faster?
Your UGG boots are precious. Instead of trying DIY methods to shorten the break-in period, try using a shoe tree. That way you don’t have the risk of damaging the boots. Even with that much pressure, a quality cedar shoe tree won’t damage the soft, furry interior of your UGG boots.

Final Verdict 

So, that’s a wrap. Let’s give a quick recap before I go away. UGG boots run a little bigger. But as the leather stretches over time, you shouldn’t size up or down. 

Go for your usual shoe size and you’ll be good to go. At first, the boots might seem a bit too cozy but that’ll pass once the break-in period is over.
