Columbia Introduces USB Powered Boots

Although USB-powered clothing and accessories are nothing new, it is only now that it is beginning to be embraced by mainstream clothing manufacturers as
Columbia Sportswear unveils its Omni-Heat boots.
The Omni-Heat is Columbia’s latest line of men’s and women’s boots that are electrically heated, thanks to its battery pack that is charged using a USB connection. It takes about four hours to fully juice up the battery, but we have no idea how long the battery could last.
The Omni-Heat boots from Columbia will be available this September. No word on the suggested retail price
