"I'm short for words—these insole warmers are fantastic for extreme winters, even in sub-zero temperatures. They're incredibly easy to use, and their longevity is impressive. An absolute must-have for winter treks!"

Works well in temperatures up to -5 to -7 degrees Celsius

Initially I was reluctant about it's effectiveness, but it proved its worth during my stay at Sarchu and Hanle. Extremely useful. Heat remains for few hours, sufficient to give comfort during night. Great value for money.

Very helpful in cold regions I used this on me Leh trip in May 2018, when the temperature at night use to fall below zero and during day 7 max.

Good product, but doesn't really gives the warmth thats expected

Useful product in cold weathers and aches n cramps

A savior while facing minus 28 degrees in Lapland.

I am using the product 2nd time.As I am satisfied from my 1st use
