Urgent recall issued for popular clothing item that threatens to cause severe burns and injuries
Thousands of pairs of socks have been urgently recalled due to the risk of severe burns.
Fieldsheer Apparel Technologies has voluntarily recalled about 45,000 pairs of its heated merino wool socks after receiving multiple reports of injuries, including burns and blisters.
An alert from the US Consumer Product Safety Commission warned 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.’
There have been 11 reports of pain and discomfort to date, the agency said. Of those, four reports were for blisters and burns.
The three models of recalled socks were MWMS05, MWMS07 and MWWS07. Each pair of socks was packaged with two lithium-ion battery packs and a charging cable.
The socks were sold at major retailers including Home Depot, Meijer and online at Amazon from August 2021 through June 2025 and cost between $80 to $130.
The socks were sold in black/gray, gray/pink, gray/orange, and black/orange color combinations and came in sizes small through extra-large.

About 400,000 to 500,000 Americans suffer burn injuries every year, with burns from hot liquids and objects like stoves and irons being the most common causes.
Burns can cause blisters to form on the skin.
Blisters that open eliminate a protective layer of skin, allowing contaminants to enter the skin. This increases the risk of infections.
Doctors have previously issued warnings about other heated products like blankets, as long-term use can increase the risk of permanent skin rashes.
The heat is usually not enough to cause a burn, but it is enough to damage or cause changes to superficial blood vessels under the skin, as well as the collagen and elastin protein fibers of the skin, which leads to the distinct appearance and discoloration.
Dr Ji Qi, a dermatologist in Baltimore, warned last year to use the lowest setting on heated products and only use them for a few minutes at a time.
Customers who bought the recalled socks are urged to not discard the lithium-ion batteries in regular trash or recycling bins due to the risk of fire. The batteries should instead be taken to a municipal hazardous waste collection site.
People who bought the socks should also immediately stop using them and contact Fieldsheer for a full refund or replacement product of equal value.
