How do microwavable slippers work?
Microwaveable slippers are incredibly easy to use. Some have inserts that you remove and heat in the microwave before popping them back into the slippers and enjoying the benefits. Others let you microwave the slippers directly to warm them up.
Either way, they normally only take a minute or two to heat up, but make sure to check the instructions before using them for the first time.
How long do microwavable slippers stay warm?
Microwaveable slippers tend to stay warm for about 30 minutes, but they can keep your feet cosy for quite a while after that, like normal slippers.
Are foot warmers good for circulation?
Foot warmers and heated socks can help keep cold feet comfortable, but they won’t treat poor circulation. If you have Raynaud’s or another circulatory condition, check with a healthcare professional before using heated products, and follow the manufacturer’s safety advice.

How we rate and assess foot warmers and heated slippers
For the products we’ve tested, we assess foot warmers and heated slippers against the criteria that matter most in everyday use:
Warmth and heating performance: How quickly the foot warmers or heated slippers heat up, how warm they get, and how evenly the heat is distributed across the toes, soles and heels.
Battery life and power source: How long the heat lasts on different temperature settings, where applicable, and whether the power source provides enough warmth for everyday use. We assess portability and ease of use, as well as the practicality of mains-powered and rechargeable designs.
Comfort and fit: How comfortable the foot warmers and slippers are to wear for extended periods, including their softness, weight, cushioning, flexibility and suitability for a range of sizes. We consider whether they fit securely, feel restrictive or provide enough room for movement.
Insulation and temperature control: How well each product retains warmth, protects against cold floors and keeps feet comfortable without becoming too hot. Where applicable, we also assess the range of temperature settings and how easy it is to adjust the heat.
Materials and overall quality: The quality of the fabrics, linings and soles, including their durability, grip and ability to retain heat. We also consider whether the materials feel breathable and whether the product is easy to clean and maintain.
Ease of use and practicality: How straightforward the products are to use around the home. We look at the accessibility of heating controls, flexibility to move around, and whether the design suits relaxing on the sofa, working at a desk, or wearing around the house.
Safety: Where applicable, we consider features such as automatic shut-off, overheat protection and secure battery connections.
Value for money: Whether the warmth, comfort, heating performance, durability and overall features justify the price compared with other foot warmers and heated slippers we’ve tested.
We use these assessments alongside long-term tester feedback to decide which foot warmers and heated slippers we recommend and which deserve a Mumsnet Best award.
