Guide To Pac Boots

A pac boot is actually named for a pac, or what was traditionally a moccasin-type soft shoe worn inside an outer shoe or boot. These liners 

can be made from a variety of materials, but they are considerably more substantial than a sock (even a thick one!). Put simply, a pac boot is a boot with a removable lining.

Picking the Right Pac Boot Liner

As you might guess, the inner lining of a pac boot serves to add warmth in extreme cold. The thicker the liner and more layers it has, the warmer the pac boot will be. However, there are several key elements that any quality liner should have to keep feet warm the whole time you wear them and not just in the first few minutes. Here are the top 5 things to consider:

  • Insulation - This can be made of polytech foam or other material, but the quality and thickness of the foam will act as both insulator and cushion for your feet. 

  •  Thermal Properties - The best liners will have a thermal membrane that reflects heat, thereby containing and actually using your body's heat to enhance warmth for your feet. 

  • Wicking Layer - One of the worst enemies of warmth is moisture. Your pac liner must wick moisture, especially sweat, away from your feet to maintain warmth. 

  • Moisture Funnel Layer - Once moisture is wicked away, it has to go somewhere. A hollow fiber layer funnels moisture and water vapor away from the foot for maximum warmth and comfort. 

  • Cushion Layer - Just because you have insulation doesn't always mean you have cushioning for comfort. We suggest a liner with a layer that provides soft cushioning for less foot fatigue and stress. 

 Features You Should Look for in a Pac Boot

While the pac boot liner is an extremely important feature, there are several others to keep in mind that will make choosing 

the right pac boot much easier. Here are the most important features to look for:

  • Height – Pac boots range in height, from 9” to 13”. The taller the boot, the warmer and more protected your ankles will be. However, a taller height also adds weight. If you will be going on short walks or not participating in strenuous activities, a taller boot will work for you. However, if you will be hiking, walking or constantly moving, you will probably want to try a 9” – 10” boot for less fatigue.

  • Temperature Ratings – If you are going to be in extreme cold, you are likely going to need a pac boot. RefrigiWear pac boots are all assigned a comfort range to guide you in the right direction. These ranges are from 10°F all the way to -120°F. Keep in mind things such as health, activity levels and other clothing can effect overall warmth.

  • Water Resistance – Depending on your situation, you may want to look for a waterproof, or at least water-resistant, pac boot. Cold water seeping in through you boot will make it impossible to stay warm.

  • Safety Elements – Many pac boots come with a safety toes and plates on the sole, some event puncture-resistant. If you are going to be in dangerous environments or areas where you might come into contact with sharp objects, look for composite or steel toes and puncture-resistant plates. 

Socks and Pac Boots

Though pac boots can be worn without socks because of the liner, many still choose to wear socks to avoid frequent liner cleaning or replacement. Make sure to stay away from cotton socks with pac boots or any heavily insulated boot because cotton absorbs and holds moisture. Instead, choose a material that has better moisture wicking properties, such as acrylic, polyester or a wool blend. Socks are an important factor when it comes to keeping feet dry.
