    NORTHBOROUGH, Mass., Dec. 20 /PRNewswire/ -- Forget heavy socks this
 winter, ToastyFeet(TM) insole liners have just been introduced by Polar Wrap.

     "Most people don't realize it, but beyond heavy socks, there is no real
 underfoot insulation for cold feet," said Bruce McCormick, president of Polar
 Wrap, the company that created the insole liners using patented nanotechnology
 from Aspen Aerogels.
     In fact, ToastyFeet(TM) just might protect you from cold symptoms.
     As reported by Reuters on November 14th, British researchers claimed that
 exposing bare feet to cold water for 20 minutes increases a person's chance of
 getting cold symptoms.  The researchers said that cold feet causes a
 constriction to blood vessels in the nose which can aid the cold virus,
 according to Reuters.
     "It's clear that to keep from getting a cold, you need to keep your feet
 warm," said McCormick.  "In the winter, it often feels like you're standing on
 ice.  That's because the soles of your shoes or boots are where your feet need
 to be protected from the cold the most."
     But why isn't your footwear keeping out all of the cold?
     "Because most insulation requires loft -- like the loft in a cotton ball
 or fiberglass house insulation," said Marc Lebel, vice president of Aspen
 Aerogels, "but when you step on it, it gets compressed and loses its loft and
 therefore its insulating power."
     But Aspen Aerogels' insulation doesn't require loft.  Its structure
 contains nanometer-sized pockets of air that can maintain thermal protection
 and shape even when you step on it.  In partnership with NASA, this same
 flexible aerogel technology is being developed for next generation space
     "We are delighted to put an end to cold feet with this new, space-age
 technology," said McCormick. Recently the company tested its product by having
 people step on a block of dry ice with only the Toasty Feet(TM) insole as a
 barrier. "No one felt any cold," reported McCormick.
     Toasty Feet(TM) is available now at Wal Mart and Kroger stores across the

 products include the Heat Exchange Mask that traps warmth from exhaling
 breaths in order to warm cold air as it is inhaled.
     About Aspen Aerogels
     Aspen Aerogels supplies nanotechnology-enabled aerogels with insulating
 properties that outperform traditional materials by 2 to 8 times. Unlike other
 aerogel material providers, Aspen provides the thermal and acoustic
 performance of aerogels in a ready-to-use blanket impregnated with the silica
 nanostructures. This blanket format makes it easy for Aspen customers to
 conserve energy and save money in oil and gas recovery, LNG shipping and
 storage, apparel, military, aerospace and energy industries.  In addition,
 Aspen is actively developing applications in the building/construction,
 automotive and fuel cell markets.
