Do UGGs Run Big or Small? (Are They True To Size + More)

Purchasing a pair of Uggs is a long-term investment since the sheepskin boots cost an arm and a leg and can easily last between five to twenty years with adequate protection and care.

Therefore, picking the right shoe size when purchasing Uggs is important. So, do Uggs run big or small? And are Ugg boots true to size? I embarked on a fact-finding mission about this, and this is what I discovered!

Do UGGs Run Big or Small In 2025?

Generally speaking, Uggs don’t run big or small since they fit true to size. However, their fleece-lined interior flattens and molds around your feet over time, making the sheepskin footwear feel a little bit roomier. Thus, your new pair of Uggs should be tight but snug when you’re trying them for the first time to account for the stretch.

To find out more about whether Uggs run big or small, whether the chic boots are true to size, and more, keep on reading!

Do UGGs Fit True To Size?

Ideally, Uggs fit true to size regardless of whether they’re boots or trainers.

However, it’s worth noting that new Uggs should feel tight and firm at the toes and shouldn’t slip when walking. Uggs stretch approximately half their size with time and wear.

Uggs’ shearling-lined interior molds around your feet with time, the sheepskin wool compresses over time due to your body weight, and their suede exterior stretch with wear like any leather.

Therefore, when purchasing a pair of new Uggs, it’s advisable to buy fairly tight and snug sheepskin boots when you try them for the first time.

Otherwise, your trendy winter boots will become loose with wear and tear, ruining their ability to provide your feet with optimal comfort and warmth.

One common misconception among Ugg lovers is that new chic boots should be roomy and bigger than normal shoe size, but nothing could be further from the truth.

Do UGG Slippers Fit True to Size?

Unfortunately, Ugg slippers aren’t true to size.

While Ugg slippers’ innersoles and outsoles are handcrafted using the same pattern as Ugg boots, they come with an open back by and large.

These warm and cozy slippers lack the closed and reinforced heel panel that Ugg boots have, making them feel slightly bigger than Ugg boots of the same size.

Thus, when purchasing Ugg slippers, sizing down from your normal shoe size is advisable to ensure they fit even after wear.

Do UGGs Fit True to Size on Wide Feet?

Classic Uggs fit true to size on wide feet. Thus, sizing up is not needed with the classic Uggs.

Nevertheless, the same cannot be said about other Ugg styles, especially the tall and slim styles.

The slim and tall Ugg style boots don’t fit true to size on wide feet. However, the problem gets eventually resolved once they’re broken in and worn.

Regardless of style, Uggs stretch over time as they wear, and their sheepskin wool mold to the shape of your feet.

Therefore, if you find it hard to wear your Uggs due to your wide feet, it would be ideal to give them some time to stretch and see whether they get better.

If they don’t stretch over time, consider returning the Uggs or buying other larger Uggs.

How Do I Know What UGG Shoe Size To Get?

You should measure your feet size to know what Ugg shoe size to get.

Generally, Ugg boots are made with larger outsoles than other shoes to accommodate the density of the sheepskin leather they’re made from.

Thus, when shopping for a pair of Uggs online, it’s pretty normal to be uncertain about the correct shoe size that will work best for you.

Luckily, there’s an easy and effective way to determine the right shoe size to purchase if you aren’t sure.

To determine your shoe size, draw a longer straight line than your feet on white paper using a pencil or pen.

Place the white paper on a flat floor and stand on the straight line on the paper with your longest toe and heel centered.

Consequently, ask a friend to mark the tip of your longest toe and the back of your foot’s heel and repeat the steps above on your other foot.

Then measure the distance between the two marks on the paper for each foot using a tape measure and record the larger measurements.

The larger measurement between your two feet is your correct shoe size. Thus, use UGG’s conversion chart to determine the Uggs to buy.

What UGG Boots Size Should I Get?

Many Uggs lovers find it hard to know the correct shoe size to purchase since the different Ugg compositions, shapes, and styles differ in size.

Therefore, the shoe size you should get largely depends on the Ugg style, shape, and composition you choose. For instance, pull-on Uggs come in whole shoe sizes.

Luckily, UGG has developed a sizing chart for men and women that indicates the length in inches for each Ugg shoe size.

Here are the men’s and women’s Ugg boots sizing charts to help you select the ideal winter boots to keep your feet warm.

Conclusion

In retrospect, Uggs don’t run big or small since they fit true to size. Finding the right pair of Uggs shouldn’t be a hard nut to crack if you get your correct feet size.

Nevertheless, it’s important to ensure you buy tight Uggs boots when you first wear them since sheepskin boots stretch with wear and time.
