Thorlo® Lifetime Guarantee

Our socks are engineered for excellence. Our raw materials are the best in the world, and we work hard to ensure that every stitch is perfect, but even the best materials have a lifespan and will eventually degrade.  

What does Lifetime Guarantee mean?

Under the Thorlo Lifetime Guarantee, in the case of a manufacturing defect, we will issue a replacement or in select cases, store credit. Replacements will be for same style and size if available, otherwise a Thorlo associate will replace it for another similar product.

Materials and fibers do have a lifespan, which is why products that have experienced wear and tear from normal use will not be considered as eligible for this guarantee.

A copy of your receipt or order confirmation, as well as photos of product(s) showing the defect, are needed to qualify for the Thorlo Lifetime Guarantee.

This Thorlo Lifetime Guarantee covers Thorlo products sold through authorized resellers (online and retailers) or purchased through

Thorlo does not offer repairs. All other product categories are not eligible for this warranty.

Some states, provinces of Canada or countries do not allow limitations on how long an implied warranty lasts, so the above time limitation may not apply to you.

What is not covered by the warranty policy?

The Thorlo Lifetime Guarantee does not cover anything other than a defect in material or workmanship. Requests due to normal wear and tear will not be covered under this guarantee.

Misuse, neglect, theft or damage caused by accidents or natural disasters will not be covered under this guarantee.
