Types of Heated Slippers 

There are so many different kinds of heated slippers on the market. Each have their pros and cons and some may be less safe than others. Nonetheless, each and every kind is perfect for those with cold feet that want warm slippers to slip into after a long day. So without further ado, here are the different kinds of heated slippers that prove to be comfortable footwear and will make you feel like you're at the spa:

#1 Electric Heated Slippers -

This variety of heated slippers tend to be popular with people who live on-the-go. They're instantly warm at the touch of a button and don't require waiting around like a rechargeable or microwavable slipper requires. They are usually battery-operated, which means that it requires some maintenance when the batteries go out. Many varieties of electric heated slippers can be good for outdoor use, as they have a thicker sole.

#2 USB Heated Slippers -

USB heated slippers are very popular with more of everything being rechargeable these days. It's convenient for those that already have several USB ports in their home, but it's not very convenient for outdoor use since moisture and debris can enter the charging port. This also requires a waiting period to get them charged up and ready for use. But since they are rechargeable, they are less wasteful than battery-operated slippers.

#3 Microwavable Heated Slipper -

Microwavable heated slippers are very versatile and popular. These can easily be popped into any microwave for a short amount of time, and then they're ready to wear. Of course, a small drawback is that you need to wait until they're warmed up which can be anywhere from 30 seconds to two minutes. But the plus of Warmies heated slippers is that they are filled with natural material that is non-toxic. Warmies Top Selling Microwavable Slipper and all others won't every require batteries or cables, but they might not always be great to use outdoors since moisture can ruin the filling.

#4 Heated Slipper Socks -

Heated slipper socks are just as cozy and warm as slippers, but they're socks. This means they have no sole, instead they have grippy texture to keep your feet from slipping. This also means that they're not great for outdoor use since they may get ruined by the elements due to not having soles. These are great for people who want to slip into bed without clunky slippers on, since socks will stay on without effort until you take them off.

#5 Heated Booties -

Heated booties can be battery-operates, rechargeable, or microwavable. The only real difference is the style of the footwear. Booties tend to cover the entire foot and ankle whereas the slipper only covers the foot, often leaving a portion of the heel and ankle exposed. Booties also tend to be more lightweight than slippers as they don't have a sole and are more form-fitting, but not as tight as a sock. 

#6 Chemical Reaction Heated Slippers - 

Chemical reaction heated slippers are similar to the heat packs you use for your gloves in the winter time. These pouches and packs that you use require the introduction of air to make them heat up. The same principle applies to these slippers. When you wear them and "crack" the pouches of contained chemicals, air is introduced and the packs heat up. These types of slippers may only work a few times until you need to replace them, which can be costly and wasteful depending on your use.
