Getting cold feet is the body’s normal reaction to colder temperatures.

When the temperature drops and you are exposed to it, blood vessels in the extremities - such as the hands and feet, will constrict. This reduces the blood flow to these areas, which also reduces the amount of heat the body loses. Makes sense right? Your body is trying to conserve energy.

Reduced blood flow to your extremities can result in your feet and toes feeling cold to the touch, as well as sensations of dullness or numbness. Toes can also turn blue due to lack of oxygen rich blood reaching the area. This will typically go away when warmer temperatures are reintroduced and blood flow is normalized again.


Circulation issues are also a very common cause of cold feet.

A person with poor circulation will often struggle to get enough warm blood to their extremities, and may complain of cold hands and cold feet frequently.

Poor circulation can have a variety of causes. Living a sedentary lifestyle or sitting at a desk all day may reduce circulation to the legs and cause cold feet. Health problems and concerns like anxiety, stress, diabetes, raynauds syndrome and anemia can have a major impact on your circulation to your hands and feet.

This may surprise you, but being in a state of high stress or chronic anxiety can actually cause cold feet. One of the body’s natural responses to stress or nervousness is to pump more adrenaline into the bloodstream. As it circulates, adrenaline causes many of the smaller blood vessels to constrict, which decreases the flow of blood to the outermost areas of the body - your hands and feet. This biological response helps to conserve energy and prepares for a fight or flight response.

Read our blog post for more about why felted wool slippers are the best slippers for cold feet.

1.) Why natural materials like felted wool are the best choice for slippers.

There's a school of thought that says wearing clothes made of natural materials can aid in stress reduction on a cellular level. Whether you subscribe to that idea or not, we can all agree that natural fibers have a much lower impact on the environment than fabrics made from chemicals and plastics by products.

Wool slippers like Nootkas are made of all natural materials, some are even completely free of dyes for a totally organic experience. Sometimes just knowing that the clothes and shoes you are wearing came from a natural and sustainable origin can help you rest a little easier. A little bit of nature can go a long way in our modern world. 

2.) Felted wool slippers insulate and hold in body heat

Hand felting slippers


Nootkas wool slippers are felted by hand using an ancient and time proven production method. Strips of raw wool are placed in a cross hatched pattern and are rubbed by hand with soap and water to combine the layers. This is done dozens of times per slipper and creates a thick piece of wool called a "sock." The wool "socks" are again felted using agitation and water. This creates a virtually indestructible, thick textile that can be shaped into a slipper by stretching it around a shoe form called a "last."

These slipper forms are then allowed to dry in the sun for up to 3 days. The result is a slipper that is thick, seamless and has some special properties that enable it to hold in heat exceptionally well. The felting process creates a dense textile that has tiny micro-pockets of air all throughout. Air is nature's greatest insulator.

Due to the presence of these micro pockets that are created during the felting process, the wool is able to trap warm air inside the walls of the fabric, and keep it close to your feet. The ability to take advantage of any warmth your feet create is one big reason why felted wool slippers are the warmest slippers for cold feet

3.) Wool slippers wick moisture and breath - keeping feet dry

Dry feet are warm feet! Have you ever put on a pair of slippers that made your feet super warm....only to end up clammy because your feet got sweaty? Ya, it's not fun and getting sweaty feet only perpetuates a cycle of cold feet because you have to take your slippers off to let them air out and your feet get cold all over again.

Felted wool is practically engineered to wick moisture and breathe. At a molecular level, wool is animal hair that is made of keratin, a complex organic substance formed by amino acids. As a fiber, keratin has some very impressive capabilities. It is lightweight yet durable and can absorb up to 15% of its weight in water. This is how wool keeps your feet from getting sweaty and smelly inside a slipper. It pulls moisture away from your feet, absorbing it, then wicking it away to the outer layers to evaporate into the air. 

If you suffer from cold feet for any reason, we highly recommend giving felted wool slippers a try. Nootkas carries several styles of slippers and house shoes that will keep your tootsies nice and toasty.
