What Makes Heated Socks Defective and Dangerous?
Several heated socks and heated insoles use lithium-ion batteries due to their compact size and ability to heat quickly. However, lithium-ion batteries are known to fail under certain conditions.
According to the Consumer Product Safety Commission (CPSC):
“The socks can cause pain and discomfort resulting in burns and blisters when worn during high-intensity activities that generate a combination of heat, excessive friction, moisture and pressure, posing an injury hazard.”
Fieldsheer has received at least 11 reports of causing pain and discomfort, resulting in burns and blisters. The CPSC warns consumers to stop using the socks immediately.

The socks came with two lithium-ion battery packs and a charging cable. The socks have a battery pocket with either a slit or a black or gray zipper. Model MWMS05 includes a battery pack with model number MW37V122 and a four-button remote control to adjust the heat settings. Models MWMS07 and MWWS07 include Bluetooth battery packs with model number MW37V22-N. The model number can be found printed on the top left corner of the label on the back of the battery pack.
