Some Acorn Products are sized normally, using whole numbers. Others, such as some of the slippers are small, medium, large, etc. For example, the Womens' line of "Oh Ewe" slipper runs from an XX-Small to a Small, while the unisex "Sheep-On" slippers run from XX-Small to X-Large.

The charts below will help you choose your size.

Acorn boots tend to be a little wide, but still are snug. Slippers are a bit more on the loose side as well, but more flexible than the boots because of a flexible comfort sole. It's normal to experience some slippage on your heel with Acorn slippers.

The quickest way to figure out your Birkenstock European size would be to add:

30 to your American size for women
33 to your American size for men
17 to your American size for kids

Example: If you wear a ladies 8, add 30. Your Birkenstock size should be 38. The catalog chart doesn't always agree, but we have found these numbers to work best.

Many styles, like the Barbados, Memphis, Oklahoma, Kentucky, run shorter, so 90% of the time you're going to need to go up a size. We have more styles that run short listed at the bottom of the page. So when we say just add 30, 33, or 17, we also have to say:

However!

We have been selling Birkenstocks for over 25 years and a lot of the time it just isn't that easy. The adding 30, 33, or 17 method mentioned above is a good starting point but we have spent a lot of time preparing the information at BirkenstockBeach.com to help our customers.

Chookas tend to fit true to size. Their boots can run a little wider when compared to the other brands. In the case of dealing with a half size, Chooka recommends that it is best to round down to the nearest full size. While the boots will be snug in the beginning, they will eventually stretch out a little and form to your feet. They will become very comfortable, but may take just a bit longer to break in since they have an outer cowhide layer.

Emu footwear runs true to size. In the case of a half size, Emu reccomends rounding up to the nearest whole size. Width is fairly standard, and seems to fit most people just right.

Emu Size Scales for Boots, Slippers, and Shoes are below.

The Koolaburra classic tall and classic short products are true to size. They seem to fit just right. When dealing with a half size for slip-ons, lace-ups, and slippers, it is recommended that you purchase up to the nearest size.

However, if you have very narrow feet, Koolaburra recommends that you order your footwear to the next size down. Koolaburra boots tend to fit more snugly than other brands because they usually include more sheepskin lining. This provides exellent insulation, which is well-appreciated by many Koolaburra customers.

Unisex sizes are quoted in mens sizes, so if its a unisex size 6 it is a 6/7 meaning "mens 6" and "women's 7".

Sven recommends that you should generally round up a size for their and sheepskin boots and clogs. The company uses a European sizing system since they are based in Sweden. The rule of thumb is to add 31 to women's American sizes and 33 to men's American sizes. For example, a woman who wears American size 8 should order a 39.

UGG footwear should be snug, but not uncomfortable. Their footwear will give a bit as it molds to your foot. UGG's products are designed to be worn barefoot (as most sheepskin products are) to maximize the cushioning and the proper warmth of the sheepskin. Their fleece footbed will mold to the natural contours of your foot, creating a personalized arch support.

Sizes generally run large in both length and width, espcially for "classic" styles.

A note about size variations

At SheepskinShoes.com, we will try our best to match your order with the correct size. Due to the fact that UGG are made in Australia, New Zealand and China, the actual size of the product may vary. We may adjust your order if we see that you tried to order a half size. When this happens, we will choose a whole size for you in an effort to match the appropriate size depending on where the particular item is from.

Tips for specific styles
Ultra Short/Tall, Sundace II, Sundance Short, Classic Short, Classic Tall, Clogs, Slippers, and the Adirondack Collection

UGG Australia recommends that you select a size smaller than your normal size for the above styles, because these products tend to be a half-size to a whole size too large and have a tendency to fit loosely. If you wear a half-size you should probably round down!
