What are microwavable slippers? 

Microwavable slippers are exactly what they sound like: reusable heated slippers that you can pop into the microwave to keep your feet warm for up to an hour at a time. Warmies microwavable footwear can be used for indoor or outdoor use and won't damage your microwave no matter how many times you need to reheat them, just be sure to keep them clean.

How do Warmies® microwave slippers work? 

Warmies microwavable slippers don't warm up on their own like rechargeable heated slippers but they are the warmest slippers for cold feet. The heating process of microwave slippers is quite simple, as all you need to do is place the Warmies slippers into the microwave for the recommended amount of time (anywhere from 30 seconds to a minute depending on the microwave).

Warmies microwavable slipper heating technology comes down to the type of filling that is used. Many other microwavable slippers on the market have a variety of plastic filling (weighted and unweighted) that can retain heat just fine, but plastic filling such as this can pose a health risk as plastic can leach toxins when heated. These toxins are not great to have in a place like your microwave. 

Warmies products are filled with natural fibers, such as flax. Flax is capable of retaining heat for up to 40 minutes or longer without posing any risks, making it the ideal material for the microwavable slipper warming process. Warmies products also have real French lavender which releases a relaxing aroma. 

The Year Round Benefits of of Warmable Slippers 

Microwavable slippers aren't just to keep your feet warm and cozy. These kinds of relaxation slippers can be used for all sorts of reasons beyond basic comfort:

  1. Pain Relief - Being on your feet all day can end in your feet muscles feeling sore. Your regular run-of-the-mill slippers might not be enough to soothe the aches, whereas the warmth of microwavable slippers will be enough. Heat is a popular tool in pain relief, as heat dilates the blood vessels increasing blood flow to the muscles. If your pain is due to inflammation, you can also find relief by freezing the slippers.
  2. Improved Circulation - As mentioned earlier, warmth dilates the blood vessels which improves blood flow. This means that using microwavable slippers can improve the circulation in your feet. Many who experience poor circulation in the feet might be suffering from things like obesity, diabetes, or heart conditions. 
  3. Relaxation and Anxiety Relief - If you suffer from anxiety or have a hard time relaxing, Warmies microwavable slippers can be of use. The filling inside includes real French lavender, and lavender has been proven to have calming and relaxing effects.

How to use microwavable slippers correctly 

Now that you're considering Warmies micorwavable slippers or already have them, you need to know how to use them correctly. Correct use will keep your Warmies slippers clean, intact, and functioning for years. So here are things to keep in mind when using your slippers as well as how long to microwave Warmies:

  • Heating In the Microwave - Warmies recommends that you don't leave your slippers for more than 2 minutes at a time. The amount of time that you leave your slippers in the microwave will depend on the strength of your microwave, but typically heat up time will range from 45 seconds to a minute and a half. Be sure to read the instructions that come with the slippers.
  • First-Use Moisture - It's common for Warmies products to feel a little damp after microwaving them for the first few times. This is completely normal due to the natural moisture content of the filling material. This will stop happening after the first few uses, but you can always place a towel with the slippers for the first few uses to absorb any moisture.
  • Monitor Temperature - If your slippers are overheated, do not put them on. If they are too hot they can damage your skin. Excessive overheating can also damage the product entirely. Let the slippers cool sufficiently and don't let them sit in the microwave unattended for long periods of time.
  • Freezing - If you want your slippers to cool your feet, simply place them in a freezer bag and put them in the freezer for roughly 2 to 3 hours. Cold will help with inflammation, bruising, and common injuries such as that. 
  • Clean Up - If your slippers get dirty, do not place them in the washer or submerge them in water. This will destroy the filling and prevent it from functioning properly in the future. Instead, use a clean damp cloth to clean the slippers. You can use small amounts of stain removing products if you have tough stains. 
  • Guidance on Reheating - Each and every one of Warmies' products are designed to be used and reheated over and over again. All that you need to do is follow the guidelines above and ensure that you are letting the product cool in between reheating them to prevent damage.
