Health Canada warns Canadians that heated socks from various field-share brands are being reminded of concerns that products can cause blisters and burns.
Merino wool heating socks and Premium 2.0 Merino heating socks are affected, but so are other versions of Premium 2.0 sold under “different mechanisms for holding the battery unit”.
The second premium unit uses a zipper or slit on the battery.
According to the recall, heated socks can cause burns and blisters on the feet of consumers due to a possible combination of heat, excessive friction, moisture and pressure.
As of July 29, there have been 19 reports of incidents in Canada, with one injury reported. The US has also reported 10 incidents and one injury.
