Our company was established in 1947 in England. At that time the company used to trade yarn. The last few decades our company has been manufacturing, importing and distributing socks.

Our North American office is based out of Oakville, Ontario in Canada. We have multiple warehouses and fulfillment centers. Shipments for this website are serviced through our fulfillment center in North Carolina.

Heat Holders were developed by our talented product development team in house. The challenge was to make a sock that would be the warmest sock ever and comfortable and practical to wear in daily life. It wasn't easy, but our team came up with Heat Holders in 2008.

Since then we have sold more than 20 million pairs worldwide and our distribution continues to grow. This growth is because of our customers who are truly satisfied with Heat Holders. Whether they are at Home, at Work or at Play in the cold winter months, there is a pair of Heat Holders for them which keeps them warm, comfortable and safe. We hope to count you among our customers!
