At FNDN, we believe it's not about where you are, but where you are from.

There's an old saying that each generation is most like their grandparents. In our grandfathers' America - before the Internet, cell phones, and video games - our "greatest generation" was a well-oiled industrial machine running wide-open with the Motor City at the heart of it all. FNDN's foundation happens to be firmly rooted in Detroit and that same innovative spirit is part of our DNA.

Our products share that same mold our grandparents valued. The industry, the inventions, the manufacturing, and even the music has branded a loyal, patriotic, hardworking ethos into us. Combining quality materials, craftsmanship and utilizing cutting edge technology, we strive to create the finest products available that are both beautiful and functional.

The item ordered was good and met expectations. Delivery however wasn't as impressive. Took about 3 weeks and emails to seller to get things delivered.

Got them for my husband who has everything--including cold feet. He loves them. If my feet were bigger, I would be reminding him that "sharing is good."

Warm only at the toe portion

I opened these up today and they work pretty great... but they only seem to heat the front area where my toes are at. No heat underneath the heel.

I have your heated socks and I really love it. I purchased these socks so that I could have an extra to keep. I will bring them home to China.
