THOR·LON® trademark acrylic yarns are exclusively developed for our Thorlos construction. "Trapped" perspiration in the shoe environment tends to "flatten" or crush common acrylic yarns. THOR·LON® acrylics are specially spun to maintain both softness and resilience, which maximizes foot comfort, blister protection and product durability.

INVISTA manufactures this fiber with a unique four-channeled cross section that produces a soft, cotton-like yarn with such superior moisture transport qualities that skin temperatures prove perceptibly cooler in comparison yarn testing. Thorlos with Coolmax® provide excellent blister protection while keeping you comfortably cool.

Thick Cushion
Our thick density padded Thorlos provide the greatest level of protection and comfort found anywhere today. This is what made the brand famous; some of our long-time customers have come to call these "Classic Thorlos".

Moderate Cushion
We make a moderate density sock product for activities that place less stress on the foot. We recommend these for short distance activities.

Thin Cushion
While we recommend our thick protection Thorlos to everyone for maximum protection and comfort, we recognize some activities place much less stress on the foot.

We also realize that many younger activity enthusiasts prefer to actually "feel more of the road" as they run. For these customers, we make a thin cushioned Thorlos that provides more protection and comfort than any thin sock on the market.
