foot warmers?

[highlandfarmwv]

This is probably a really dumb question, BUT: Can you use those chemical foot warmers in the water? Or does water touching them render them inactive? I am talking about the ones that you shake or otherwise and they provide warmth for a few hours. Thanks.

This is not a dumb question and I'm glad you asked. I don't know the answer so I'll be watching this thread.

I've wondered if you can buy neoprene socks, too, but I always forget to ask my LDS. My bootiesare a little loose.

Neoprene socks rock. They fill gaps in oversize boots, add padding for long walks to the entry site, and add warmth in cold water. They are cheap, too. If your LDS doesn't carry them, check out a fishing tackle store.

I think the dry ones that activate when you expose them to air don't work so well in water.

There are some other ones that are re-usable and liquid filled that you activate by flexing a disk- then the liquid starts to crystalize and warms up. That type would probably work, but you might not want to go around walking on them....

You've tested this?


Oh- I thought you meant the battery powered socks...

they might work in a dry suit but if you flood you might have a bad cemical reaction that you dont want

There are more than 1 kind of warming device that i am aware of. 2 in particular that i am thinking of are the Dry ones in a sack of some sort...these are the most comon ones, and they will not work after being submerged, as they depend on the air for the chemical reaction that "warms" them. There is another type however, a reusable one. They are self contained in a clear plastic bag that appears to be full of a clear liquid and have a silver tab in the bag. When activated by bending the silver tab in the bag the clear liquid turns to a cloudy haze of crystals and it heats for around 20 minutes. These type are self contained and will work under water. After use they can be boiled untill the crystals turn into a clear liquid again for re-use....I hope this helps.

My philosophy is this "There are not dumb questions, only those that you do not ask!"

I've never tried the shake up warmers in my boots. I have used them in the pockets of my dry suit undergarment and it works great!

If your feet are getting cold, maybe try a set of polypropelene socks or neoprene socks. The poly socks are a little thinner and work great in all water temps. I use them everywhere, they even help to get your boots off faster. The neoprene socks are much warmer but have a tendency to keep my feet floating behind me. If you have negatively buoyant fins you should be OK.

Hope this helps!

You wouldn't want to put those chemical reaction heat pads under a wet suit. It certainly sounds like a great idea. However it is not so great in practice. Sure you'll be nice and warm for the first couple minutes, but after that you'll be hot... 5 minutes in and the heat will be too much and you'll actually start to damage your skin.

What makes them great for above water use is that you can warm up.. then move them. Your skin is not directly in contact with the heat for any real length of time. Not so when it's pancaked between you and your lower back in a wet suit.
