Cold feet are a common and often uncomfortable problem for elderly people, particularly those with poor circulation, who spend a lot of time sitting, or who feel the cold more than they used to. Heated foot warmers offer a simple, practical way to keep feet warm at home. This guide looks at several options to help carents find what might work best for their parent's routine and level of mobility.

Disclaimer
The products featured in this guide are general-use heated foot warmers and slippers and are not medical devices. Poorly fitting footwear is a known contributor to slips, trips and falls in elderly people, always ensure any slipper or foot warmer fits securely and does not slip on the foot, and that the sole provides adequate grip on the flooring in your parent's home. Electric and USB-heated products should never be used while sleeping or left unattended while in use, and should be switched off when your parent is moving around. Do not use heated products on feet or legs where circulation is poor, where sensation is reduced, or where your parent cannot reliably feel if something is becoming too hot, always seek medical advice first in these circumstances. Always follow the manufacturer's guidance on maximum heating times and temperature settings. If your parent has a history of falls, reduced mobility or balance difficulties, speak with their GP or occupational therapist before introducing new footwear. All products are used entirely at your own risk. Carents accepts no responsibility for any injury, burn, fall or adverse outcome arising from the use of any product featured on this page.

2. OhMill USB Heated Floor Socks and Slippers
Knitted slipper socks with a USB-powered electric heating pad that maintains a constant warmth enough to be comfortable without the risk of overheating.
