Nearly 208,000 pairs of battery-powered heated socks sold exclusively at Costco have been recalled due to a burn hazard.

The U.S. Consumer Product Safety Commission announced the voluntary recall on Thursday, April 23, involving 32 Degrees Heated Socks in medium, large and extra-large sizes, all black. The socks, which include a rechargeable battery pack, user manual and packaging marked with "32° HEAT," were sold at Costco stores nationwide and online at Costco.com from August 2025 through March 2026 for between $30 and $46 per pair.

Officials stated the socks pose an injury hazard, including burns, when worn during high-intensity activities that generate a combination of heat, excessive friction, moisture and pressure. The heat sensors are concentrated in the forefoot area, and the battery provides up to eight hours of use. The socks consist of a blend of cotton, polyester and spandex and were manufactured in China by importer David Peyser Sportswear, doing business as 32 Degrees, based in New York.

The CPSC has received 14 reports of heat-related incidents associated with the socks, 13 of which involved first- or second-degree burns. One Costco customer reviewer described experiencing a second-degree burn on the ball of the left foot after using the socks at level 3 heat setting for two hours inside ski boots.

Consumers are urged to immediately stop using the heated socks and return them to any Costco store for a full refund. No receipt is required for the return.

The product, recall number 26-435, was designed for cold-weather activities like skiing, where users might engage in strenuous exercise. Costco has been processing refunds since the announcement and sent letters to members about the recall. Neither Costco nor 32 Degrees immediately responded to requests for additional comment from media outlets.

This recall highlights risks with wearable heated apparel during intense physical activity. Previous heated sock recalls, such as those by Fieldsheer in 2025 and Tech Gear in 2019, involved similar fire and burn concerns but were unrelated to this product.
