Latest Updates
On August 7, 2025, Tech Gear 5.7 Inc., doing business as Fieldsheer Apparel Technologies of Carlsbad, California, announced a voluntary recall of its heated socks in cooperation with the U.S. Consumer Product Safety Commission (CPSC) [1]. Approximately 45,000 units are affected in the United States.
What Products Are Affected?
The recall covers three models of Fieldsheer heated merino wool socks, sold in sizes small through extra-large. Each pair came with two lithium-ion battery packs and a charging cable. The orange Fieldsheer logo appears on the front of each sock. The affected models are:
- Model MWMS05 – Merino Heated Socks, available in black/gray. Includes battery pack model MW37V122 and a four-button remote control to adjust heat settings.
- Model MWMS07 – Premium 2.0 Merino Heated Socks, available in black/orange and gray/orange. Includes Bluetooth battery pack model MW37V22-N.
- Model MWWS07 – Premium 2.0 Merino Heated Socks (women’s), available in gray/pink. Includes Bluetooth battery pack model MW37V22-N.
The model number is printed on the top left corner of the label on the back of the battery pack. The recalled socks were sold at Scheels All Sports, Fred Meyer, Home Depot, Meijer, Bomgaars Supply, Buchheits, Running Supply, Fleet Farm Wholesale Supply, and other nationwide retailers, as well as online at Amazon.com, from August 2021 through June 2025 for between $80 and $130. The socks were manufactured in Bangladesh.
What Is the Hazard?
When worn during high-intensity activities, the recalled heated socks can generate a dangerous combination of heat, excessive friction, moisture, and pressure. This combination can cause pain, discomfort, burns, and blisters on the wearer’s feet and ankles, posing a significant injury hazard — particularly during activities such as skiing, hiking, or other vigorous outdoor pursuits where the socks are most commonly used.
Incidents and Injuries
Fieldsheer has received 11 reports of the heated socks causing pain and discomfort during use. Of those incidents, four resulted in burns and blisters to consumers’ feet.
What Caused the Recall?
The recall was initiated after the company determined that a combination of factors — including the heated sock’s own heat output, friction from physical activity, moisture from perspiration, and pressure from footwear — can reach dangerous levels during high-intensity use. Under those conditions, the socks can cause thermal injuries to the skin, even when operating as designed. The socks were manufactured in Bangladesh and sold under the Fieldsheer brand name by Tech Gear 5.7 Inc. of Carlsbad, California.
What Should Consumers Do?
Consumers who own the recalled Fieldsheer heated socks should stop using them immediately and contact Fieldsheer Apparel Technologies for a full refund or a replacement product of equal value. Consumers should also dispose of the lithium-ion battery packs properly. Lithium-ion batteries should not be placed in regular trash, curbside recycling bins, or standard used-battery collection boxes. Consumers should contact their municipal household hazardous waste (HHW) collection center for guidance on proper disposal.
Consumers may contact Fieldsheer Apparel Technologies toll-free at 888-908-6024, Monday through Friday, 8:00 a.m. to 4:00 p.m. PT, by email at cs@fieldsheer.com, or online at fieldsheer.com/pages/recall-information.
Can I File a Lawsuit?
Consumers who purchased recalled Fieldsheer heated socks — particularly those who suffered burns or blisters as a result — may have legal options. A class action lawsuit could allow affected consumers to seek compensation for medical expenses, pain and suffering, lost wages, and other related losses. Contact an attorney to learn more about your rights.
