Lukewarm in the toes area only
Thick insoles provide a slight warmth in the ball of the foot/toe area only. Very thick heels and midfoot/arch area have no heat at all. Directions are not translated very well and remote control is silly. There is no light on the insole to indicate if they are on or off. The way to trigger the insole to be "on" is to use the temperature up or down arrows. Light on insole goes on momentarily, then immediately off again, even if they're "on". Because they provide so little warmth, it's impossible to tell if they're on or off.  Hard to test them out of the shoe to see if they were really working or not.<br />Unfortunately, they had to be trimmed to fit in the shoe so I can't send them back.  I am so disappointed in this product. Absolute waste of money. Disposable Hotties for the shoes would be much better!
