I agree with the other reviewers that these inserts are cheaply made and the battery packs are a bit awkward, but I have severe problems with cold/numb feet, and these inserts have made it possible for me to be outdoors in the winter for the first time in over thirty years. You must be careful replacing the batteries, as the contacts in the battery holders are VERY fragile. The inserts are paper thin, so they can be used even in tight-fitting shoes, unlike battery-heated socks, which are too bulky to fit in any shoes or boots. The inserts are also better than the single-use toe warmers, because if your feet get too warm, you can simply unplug the wires from the batteries. I hope this company will improve the design and quality of these inserts--I'd gladly pay more for a better product. In the meantime, twenty bucks for these inserts is a good deal. Just make sure to also buy a AA battery charger.

I got this for my boyfriend for christmas, and he hasn't had alot of time to judge the product since it's been warm out, but these are his initial responses:

Pro: Heats up his feet quickly and they stay warm.

Cons: They can get uncomfortably hot if left on for too long. The strap to hold the batteries isn't uncomfortable or problematic, but it is inconvienent. Also, the shoe insert will slide backwards, so unless you want to adhere it to your shoe, it will become very irritating.

I ordered these foot warmers because my toes get cold and numb very easily in cool temperatures. The battery packs that strap to your legs were awkward and bulky and quickly slipped down my legs to my ankles as I walked. I felt some warmth when I first plugged the "cozy feet" in, but could not detect any heat a few minutes later. I returned the item to Amazon for a full refund.

These foot warmers are wonderful. The only negative thing I can say is that the wires can be annoying, but once you have them on, you don't notice anything except for your warm toes. You can conveniently turn them on and off as needed. I get a solid 4-5 hours out of a set of rechargeable batteries. This is my first winter with them so I cannot say how durable they are, however even if I have to buy new ones every year--they are well worth it.

First time I wore these hunting, the wire on the left one split open and shorted out. I noticed a burning against my leg, and realized the battery pack was getting extremely hot. Took a few moments to access the unit to turn it off. Rechargeable batteries have expanded slightly and the wrapping on them is split.
Sent back for refund. Also, the insoles only get slightly warm, doesn't help when the ambient temperature is below 20. Going to stick with hand warmers in each boot.

What I like about the Cozy feet heat inserts is that you can walk around freely with them any where you want to go. You don't have to plug it into a wall because it uses batteries, so your'e not confined to a particlar area. I use rechargable batteries instead of regular alkaline batteries for cost saving and convenience and it does keep you feet pretty warm for several hours. Very useful if you have cold feet in cold weather.

They thawed my feet just enough so that I feel the cold. Seriously, my feet felt better before I put them on. All they did was wake up my nerves to feel the bitter cold. I cannot send them back because they technically worked so I will probably attempt to increase the voltage which will require some work. I would not recommend these for sitting inactively in a cold humvee for long periods of time.

These are an excellent option to keep your toes warm in the winter if you have poor circulation like me. They cost a bit more than the chemical warmers, but quickly become more economical since you can use them over and over. Unlike chemical warmers they keep working even when your footwear is basically airtight like many well-insulated boots.

Runtime can also be as long as you want since you can switch batteries, but I get about 3 hrs on one set of batteries. They also take standard AA (including rechargeable) so you don't have to purchase expensive battery packs like some alternatives.

They are best used in an already warm piece of footwear though. They don't get super hot, but I find them to be the perfect temp for helping with poor circulation on cold winter days.

These things are designed for 3.0V from two alkaline batteries. The power they put out is related to the square of the voltage, so with alkaline lets just say it puts out 9W.

But rechargeable AA's have 1.2V each. Which means two puts out 2.4V. Thus the power output from a set of rechargeable batteries are 5.8W, or less by a third.

I went through the effort of getting a triple AA pack and a chip that changes the 3.6V output to 3.0V and could handle the amperage to get 9W even with rechargeables. Not a task to be undertaken unless you have a good understanding of electrical circuits.

Once I did this, my wife, a displaced Texan in Iowa, won't go outside in the winter without them. And eventhough she has to replace the batteries each day, they are rechargeable.

I just wish you could buy a set designed for this.

When I first plugged in my Cozy Feet I thought it was broken. There was simply no detectable warming. I bought another one hoping it was just a lemon. But the second one was the same way. After trying it several times I finally detected a faint, and I do mean faint, warming of the pad. I had to hold it in my hand as I plugged it in. Only then could I detect a change in temperature. I kept one and returned one. I've installed them in my ski boots. I have very low expectations when I finally hit the slopes.
