Cozy Products CF Cozy Feet AA Battery-Powered Reusable Shoe Inserts

Cozy Feet are battery operated heated shoe insoles that fit right inside any shoe or boot. The thin insoles heat up to keep toes and feet warm. Foot warmers were designed originally for military use to maintain optimal body temperature of feet in cold conditions. These insoles differ from others as these can be recharged on the go by using fresh or rechargeable AA batteries. The battery unit is included on a belt clip, so you don’t have to remove shoes to recharge the inserts. Inserts themselves are attached to the battery unit via a 57 inch cord (just over 4.5ft) which is retractable and fully adjustable to meet any height (the smallest the cord retracts is 6” – shoe inserts will fit any size shoe from adult men, women, and children sizes 2+). For reasons of safety, this in-shoe warmer is designed to keep heat just above normal body temperature. It does not create noticeable hot temperatures, since elevated temperatures in contact with the body may lead to injury. Cozy Feet works by keeping shoes at a comfortable, safe temperature.

Five Tips for Buying a Heater
Choosing a space heater is a matter of sifting through a bewildering array of types, power ratings, and fuel sources. Let's break it down a little to make the process easier.

What are the different types of space heaters?

• Radiant heaters emit infrared radiation that directly warms the objects in front of the heaters (rather than the surrounding air). If you only need heat by a desk or in a small section of a room, a radiant heater is quiet and will use very little power.
• Forced-air heaters use a fan to blow air that has been warmed by metal or ceramic heating elements. A forced-air heater is appropriate for quickly heating up a small- to medium-sized room, but can be noisy.
• Convection heaters draw cold air from the floor; the air is warmed by heating coils and emitted from the top of the heater. A convection heater is appropriate for quickly heating up a small- to medium-sized room, but also can be noisy.
• Radiators work by heating oil enclosed in a reservoir, gradually heating the surrounding air. If heating speed isn't an issue, you might want to opt for a radiator. These are extremely quiet and effective--perfect for bedrooms.

Should I buy an electric or a combustion model?
If you want a heater that will be available in emergencies, or that can heat areas larger than a single room, choose a "combustion" model--one that is powered by a gas or fuel like propane, kerosene, natural gas, or diesel. Which fuel type you choose depends largely on convenience and local availability. For example, diesel would be appropriate for a heater you take with you on long car trips.

How powerful a heater do I need?
Heaters are rated by BTU, which stands for British Thermal Unit (the amount of heat needed to heat one pound of water by 1 degree F). To find out how many BTU you need:

• Calculate the volume of the space to be heated by multiplying square footage by height.
• Multiply that number by 4 if your insulation is poor, 3 if it's average, or 2 if it's good.

The resulting number is a ballpark figure for how many BTU you'll need.

Do space heaters cost a lot to operate?
As a general rule, electric space heaters are more expensive to use than combustion models. To ensure energy efficiency, a thermostat is a must-have feature for any heater. For radiant heaters, models with a 360 degree heating surface can heat larger spaces. If you need a forced-air heater, models with ceramic elements tend to be more efficient.

Are space heaters a fire hazard?
Space heaters are implicated in about 25,000 residential fires every year. To ensure proper safety, always follow the manufacturer's usage instructions and fill out the warranty card to receive informational updates from the manufacturer. Also, look for extra safety features such as an automatic shutoff switch that can shut down the unit if, for example, it gets upended. In addition, choose a model where the heating element is adequately enclosed within the unit.

WHAT YOU WILL FEEL:
For safety reasons, this in-shoe warmer is designed to heat up to just above blood heat (normal body temperature). It does NOT create noticeably hot temperatures, since elevated temperatures in contact with the body may cause injury. COZY FEET works by keeping the temperature inside the shoe at a comfortably normal, NOT dangerously hot temperature.
