Quick Answer: It depends on what materials the socks are made from. If you're looking to create a DIY rice sock to heat in the microwave, there are certain steps you'll need to take for safety.
Let's dive right in...
What Are Socks Made Of?
Socks can be made of a wide variety of materials, including natural ones like cotton and synthetic ones like rayon and polyester.
You'll often see socks that are made out of a blend of synthetic and natural fibers. In fact, you probably have a number of garments that are cotton-polyester blends.
This is why it's important to make absolutely sure that your socks don't contain synthetic materials, which can melt, cause a fire or otherwise ruin your microwave.
Even natural materials can be hazardous for flammability reasons. However, it's not impossible to microwave natural fibers if you're cautious, turn the power level on your microwave down and watch carefully.
One more vital step is to make sure there are no metal components on the socks you plan to microwave. That includes buttons, thread and any embellishments. These can spark and create the potential for a fire.

Different Types of Sock Materials
The world of socks is diverse. Here are some of the natural materials you can typically buy socks in:
If you're going to microwave a pair of socks, stick with cotton. Many cotton products used for relieving muscle aches and pains are designed to be warmed in the microwave.
You may find other natural fiber heating pads and products that can go in the microwave, too. However, cotton fabric has been safely used in enough cases to make it a good bet.
Again, just make sure that your cotton socks are all cotton and contain no metal or synthetic materials. Even with cotton socks, you still need to be careful and watch for signs of burning.
How Do You Know If Socks Are Microwave Safe or Not?
You might not be able to tell too easily if socks are microwavable. As of right now, it's not a common enough thing to microwave them that companies would put microwave information on the packages.
But if you were to see something on the package that warns against microwaving, you have your answer.
Checking with the company that makes the socks is a good way to find out. This can be accomplished with an email or a phone call.
If you don't have success with any of these steps, just making sure that the socks are 100 percent cotton could suffice. Just keep the power level on your microwave down and monitor the socks to make sure that nothing goes awry.

Labels on Clothing to Be Aware Of
While microwave labels may not be present on clothing, flammability labels sometimes are.
A label that warns that an article of clothing is highly flammable shouldn't go in the microwave, regardless of the material.
If you don't see this type of label, don't assume that a garment has a low risk of igniting, but do follow the safety precautions as outlined above.
