We are born with thick pads of fatty tissue on the bottoms of our feet commonly called "fat pads," that protect the bones, blood vessels and nerves. It turns out that by the time many of us have reached the age of 40, we've lost as much as 50 percent of those fat pads due primarily to the shearing forces that come from walking and running on man-made surfaces.

Thorlos socks protect the fat pads by providing exclusive, protective, cushioning fabric under the bottom surface of the foot. The shearing force is then transferred from the foot to the sock. Thorlos specially-engineered cushioned fabric helps to replace the function of our natural fat pads. The result is better protection and better-feeling feet! Thorlos come in 32 different activity-specific styles including running, walking, tennis, hiking and skiing.
