Keeps toes warm all day
Used these while skiing last weekend. Connected them to a power bank in my pocket and my feet were warm the entire time. The ultra-soft fleece is very comfortable.

Perfect for my morning walks
These insoles are a game changer for winter mornings. They heat up quickly and stay warm without getting too hot. The fleece is incredibly soft against my feet.

Great warmth, slightly bulky
Works exactly as described. My feet stay toasty during my shift outdoors. Only downside is they add a little bit of height, so tight shoes might feel snug.

Best purchase this winter
I have poor circulation and these help immensely. The constant temperature feature means I don't have to worry about adjusting anything. Highly recommend!

Good value for money
For the price, these are fantastic. They aren't as hot as some battery-powered versions I've tried, but they are consistent and comfortable for long wear.
Q: Can I use these with a standard phone power bank?
A: Yes, these insoles work with any standard USB power source, including most smartphone power banks that output 5V.
Q: Are these insoles washable?
A: The insoles themselves should not be submerged in water. You can wipe the surface with a damp cloth. Please disconnect the USB cable before cleaning.
Q: What is the warranty period for this product?
A: We offer a 1-year manufacturer warranty covering defects in materials and workmanship. Please contact our support team with your order number for claims.
Q: Do these get hot enough to cause burns?
A: No, the constant temperature technology is designed to maintain a safe, comfortable warmth specifically to prevent overheating or burns.
Q: How do I trim them to fit my shoe size?
A: There are dotted cut lines on the bottom of the insole. Simply place your current insole on top for comparison and cut along the line that matches your size.
