If winter chills you to your toes, there are all sorts of hot solutions for the shivers these days.
The best part is many new products for cold toes and fingers use rechargeable batteries, for safe, effective warmth.

If your main chill situation is walking in January, try some rechargeable gloves. You plug them in as you would your phone. When they are powered up, the gloves will stay warm even around your fingers for hours — long enough to walk your dog or get to your car at the grocery store.
The drawback to the rechargeable gloves is that they are not exactly fashionable. Most are bulky and thick.
If you like your own gloves, but hate icy fingers, try a rechargeable electric hand warmer. There are many brands, but one by ocoopa is shaped just right to keep in your pocket and wrap your fingers around. Hand warmers stay warm for about four hours and typically sell for about $25 to $30.
But what if your fingers just get cold while typing at the computer? There’s a device for you. A number of fingerless gloves plug into a computer USB port and heat the top and bottom of your hands while you type. About $15.
For a bus or taxi ride, maybe a rechargeable muff can do the trick. These have a strap that goes around the neck and plug into a USB port to power up. About $15 to $25.
If you just have cold fingers while watching TV in bed, try a rechargeable hand pouch. About $15.
A variety of heated socks are available as well, but the rechargeable socks can run over $60.
