As the cold months of winter approach, is it time to bundle up and fight off the cold. While you can layer on the sweaters and long underwear, your extremities are the hardest to keep warm, especially in bitterly cold weather. Most people complain that it is their feet that feel cold the fastest and if you are outdoors for prolonged periods of time, frostbite can be a real hazard for improperly insulated toes. You can add extra layers of socks and even heat generating inserts, but one of the best things that you can do to keep your feet warm during the winter is to don a pair of fur boots.

If you consider than any mammals has some variety of fur or hair on it, fur has been used to keep organisms warm for millions of years. Even humans began to wear the fur of other animals to keep warm over ten thousand years ago.

Fur is great insulator because it is multi-layered. The under layer is created but soft and thin hair that has a downy texture.

Most fur boots that you will find on the market today are called ugg boots. This same, and the attendant style, were popularized in Australia during the seventies.

The inner part of the boot is full of soft fleece, the wool that can be clipped from the sheep while it is still living. However, the outer part of the book is made from treated leather. This combination of sheep leather with the wool still attached is the most popular type of animal fur worn today.

The style of uggs is unisex and fairly standardized. Regardless of color combination and stitching detail, the top of the boot extends in a tubular fashion to about halfway up your calf. The sole give you around an inch of height.

The toe is rounded, giving the whole boot a "cute" and chunky look. These fur boots are all the rage across the United States as they are perfect for keeping your feet warm as you tramp around the city streets.
