Safety Works CTFM Toasty Feet Mens Shoe insoles Infused with Aerogel for Sizes 8-12
Product Description
Toasty Feet insoles contain the insulating material, aerogel – simply the lightest and lowest-density solid known to exist. This nano-technology, used by and developed for NASA, is 50-99-Percent air, yet can hold 500-4,000 times its weight in applied force. What does that mean to you? It means the insulating material does not obtain its effectiveness from loft or thickness – so the insoles’ insulating material will not lose its effectiveness when compressed underfoot. Toasty Feet insoles effectively block the transfer of cold and heat – keeping your foot a constant and comfortable temperature. Fits in almost any shoe or boot.
