Do UGGs Run Big or Small?

UGG boots are a popular choice for their unique style and cozy comfort. But when it comes to finding the right fit, many people wonder whether UGG boots run big or small. It’s important to understand how UGG sizing works so that you can fully enjoy your boots without worrying about any discomfort or improper fit.

UGGs are made from sheepskin, a material that has the tendency to stretch over time. This means that the boots may feel a bit snug when first worn but will eventually become more roomy as they break-in. On the other hand, some styles may fit true to size despite the initial snugness; making the right choice largely depends on the style, your foot’s width, and personal comfort preferences.

Key Takeaways

  • UGG boots tend to run large, but some styles may fit true to size or be snug initially due to the thick lining.
  • Understanding how boot materials like sheepskin can affect the fit will help you make the right size selection.
  • Consult online sizing guides, try different sizes, and prioritize comfort to find the perfect fit for your UGG boots.

Ugg Sizing Basics

UGGs are popular, cozy footwear that come in a range of styles and sizes. To find the perfect fit, it’s important to understand Ugg sizing basics. In this section, we’ll explore whether UGGs are true to size and discuss some tips on how to find the right size for you.

True to Size

UGGs are known to be comfortable and warm, but when it comes to sizing, it’s crucial to consider the type of UGG boot you’re planning to buy. Most UGG boots are considered true to size, which means you should buy the same size you usually wear. However, some UGG styles, like the Classic Boots, may run slightly big, so it’s advised to go half a size smaller than your regular size.

A helpful step to determine your UGG size is to measure your feet. You can do this by following the steps mentioned on the UGG sizing information guide. It’s important to note that UGG does not offer half sizes, so if you wear a half size, you may need to size up or down, depending on the specific UGG style.

When it comes to UGG slippers and shoes, they’re generally true to size, meaning you can purchase your regular size in these products.

To simplify this Ugg sizing information, here’s a quick breakdown:

  • UGG boots: mostly true to size; size down half a size for Classic Boots
  • UGG slippers and shoes: true to size

Remember, the key to finding the perfect UGG size is understanding the specific style you’re interested in and measuring your feet to ensure a comfortable fit. With this information in hand, you’ll be well on your way to enjoying your cozy UGGs in no time.

Material and Comfort

When it comes to UGGs, material and comfort play a significant role in how they fit. Let’s explore two essential aspects of UGGs: Sheepskin and Arch Support.


UGGs are well-known for their sheepskin material that contributes to their coziness. Sheepskin is a natural insulator, providing warmth and cushioning to your feet. The soft, fluffy interior allows your feet to stay comfortable for extended periods.

Sheepskin also helps with the fit of UGGs. Since it stretches over time, UGGs tend to run a bit big. It’s recommended to go half a size down or even a full size smaller than your regular shoe size. This will ensure a snug fit as the sheepskin leather adapts to the shape of your foot.

Arch Support

Arch support is crucial for maintaining foot health and preventing discomfort or pain during long periods of wear. Some UGGs offer built-in arch support to keep your feet comfortable and well-supported.

When choosing your UGGs, be sure to consider the arch support provided by the boots. If you need extra support, you can always look into additional insoles or inserts specifically designed for UGGs or similar footwear.

With the combination of sheepskin material and proper arch support, UGGs can be incredibly comfortable and versatile. Keep these factors in mind when selecting your perfect size and style.

Determining the Right Fit

To find your perfect pair of UGGs, it’s crucial to consider both the width and foot length when making your purchase. In this section, we’ll explore how to account for these factors and cater to wide or narrow feet.

Width and Foot Length

When selecting a pair of UGGs, it’s essential to determine the right fit for your foot length. In general, UGG Classic Boots run big, so you’ll want to buy a pair that is half to a full size smaller than your typical shoe size. This is because they are made of sheepskin material, which is known to stretch out over time.

To find the perfect fit, follow these steps:

  1. Measure your foot length: Place your heel against the wall and measure the distance from the wall to the tip of your longest toe.
  2. Consider the width: UGGs are generally designed for an average width, but they can stretch to accommodate thicker socks or wider feet.

Here’s a simple sizing chart to help you find your ideal UGG size:

Wide and Narrow Feet

For those with wider feet, it may be beneficial to size up when purchasing UGGs. This is because the sheepskin material will stretch and mold to the shape of your foot, providing a comfortable fit. On the other hand, if you have narrow feet, you might want to size down to ensure a snug fit.

Keep the following tips in mind when shopping for UGGs:

  • For wide feet: opt for UGG styles made of sheepskin, as they’ll stretch to accommodate your foot width.
  • For narrow feet: consider UGG styles with a more structured design, which will provide a better fit.

In conclusion, finding the right fit for your UGGs involves considering both the width and foot length, as well as accounting for wide or narrow feet. By following these guidelines and using the sizing chart provided, you should be able to find the perfect pair of UGGs for your feet.

Ugg Sizing Strategies

When it comes to finding the perfect fit for your UGGs, there are several factors to keep in mind, such as whether the boots run large or small, and how to properly adjust for half sizes and full sizes. In this section, we will dive into the world of UGG sizing and address various strategies to help you find your ideal fit.

Half Sizes and Full Sizes

UGGs generally don’t come in half sizes, so it’s essential to adjust your sizing choice accordingly. When it comes to regular-sized UGGs, if you’re between sizes (e.g., you wear a 7.5), you should typically order one size down (e.g., a size 7) to ensure a snug fit, as the boots will mold to your feet over time.

Sizing Chart and Reviews

To find the best possible fit, it’s essential to refer to the UGG sizing chart and read customer reviews. The sizing chart will provide you with a guideline, while reviews can offer helpful insights into how the boots fit based on real-world experiences. Keep in mind that some styles or materials, such as Classic UGG Boots, might run larger than others, so it’s crucial to observe specific details for each product.

When to Size Up or Down

As a general rule, UGGs tend to have a snug fit initially, but they will eventually mold to the shape of your feet. Classic UGG Boots, made of sheepskin, are known to run large, so you may want to size down by half to a full size to accommodate the natural stretch of the material. However, some UGG products, like slippers, may run true to size. In such cases, make sure to consult the sizing chart and customer reviews to determine the proper sizing strategy.

When in doubt, don’t hesitate to reach out to UGG customer service or visit a store to try on various sizes before making a final decision. The right fit will ensure maximum comfort and enjoyment of your UGGs for years to come.

Caring for Your Uggs


Caring for your Uggs is essential to keep them in the best condition. When it comes to washing your Uggs, it is not recommended to put them in a washing machine. Instead, gently hand wash them using a cloth and a mild detergent diluted in water. Make sure not to soak the boots or expose them to direct water, as this can damage the materials. Gently blot the boots to clean them, and then let them air-dry away from direct heat or sunlight.


It’s crucial to understand that Uggs may shrink if not cared for properly. Exposing them to water or heat can cause the sheepskin to shrink and lose its soft, comfortable feel. To prevent shrinkage, avoid exposing your Uggs to excessive water and high temperatures. This means you should also avoid using a heat setting dryer.

If your Uggs happen to shrink, there are ways to restore them to their original size. One method is to gently stretch them by stuffing them with paper or a towel. This will help expand the material and restore the proper fit. Another option is to wear them while they are still damp from cleaning, as this will allow the material to stretch and mold to your feet. However, be cautious not to overstretch them, as this could lead to permanent damage.

Additional Tips and Tricks

In Between Sizes

If you’re in between sizes when it comes to UGGs, it’s usually best to opt for the smaller size. This is because Uggs tend to stretch a little over time, so a snug fit at first is ideal. Wearing socks with your UGGs can make a difference in the initial fit. Thin socks are generally recommended, as thicker ones may make the boots too tight initially.

Here are some tips for wearing socks with Uggs:

  • Choose thin socks for a comfortable fit
  • Avoid thick socks as they may make the boots too tight
  • Wearing your Uggs without socks is also an option


When you first get a new pair of UGGs, they might feel tight because of their thick lining. Over time, as you wear them, the material will settle and become more roomy. If you find that your UGGs are still too snug and you want to help speed up the stretching process, a shoe stretcher is an option.

Here’s a simple guide on using a shoe stretcher for your UGGs:

  1. Insert the shoe stretcher into your UGGs, making sure it’s properly positioned.
  2. Slowly turn the handle to widen the stretcher, which will stretch the interior lining.
  3. Leave the stretcher in for a few hours or overnight, then remove and try on the UGGs for comfort.
  4. Repeat the process if more stretching is needed.

Remember to measure your feet using the heel-toe measurement method to get an accurate size for your UGGs. Compare the measurements to available sizing charts, and always consider the factors discussed above for the best fit.

To summarize, when working with UGGs sizing, account for factors like:

  • In between sizes? Opt for the smaller size
  • Wearing socks, especially thin ones
  • Allow for initial tightness and natural stretching
  • Use a shoe stretcher if necessary
  • Rely on heel-toe measurements and size guides to determine the best size for you
