How We Do It

Fiber First® Moisture-Wicking

For us, fibers come first. We select only the highest-performance natural and synthetic fibers with inherent moisture-wicking capabilities, rather than treating our fibers with chemicals that are harmful to the environment. Our signature Olefin fiber is not only environmentally responsible, but also durable, breathable, and moisture-wicking like no other. 

Contoured Compression®

All of our socks are thoughtfully designed to support the contours of your foot, providing the perfect fit and support for every exercise or adventure. We know that every athlete has different needs and preferences, so we offer a wide range of compression levels. From maximum stability for high-intensity sports to gentle compression for lighter activities, we’re here to support it all. 

Sock Features
Signature Olefin fiber Wicks moisture quickly to keep feet dry and blister-free
Channeled Upper Increases breathability to keep feet cool
Seamless Toe Box Eliminates any friction around toes for a comfortable fit
Archband Support Maintains shape, keeps socks in place, and firmly supports arch
Y-shaped Heel Creates a snug fit that moves with your foot without any bunching or slipping
Our Proprietary Features
GripDry™

This proprietary fiber blends an advanced polyester nanofiber with our responsible Olefin fiber, providing excellent moisture-wicking and a slight grip for added stability.

Used in our Flite XT and Flite XT Trail socks.

AnkleLock™

Uses strong elastic to wrap your ankle and heel, offering unparalleled ankle support, particularly during repetitive movements.

Featured in our Flite XT and Flite XT Trail socks.

Our Materials
Olefin

Our Aspire, Vision, Flite XT, and Flite XT Trail lines are the only performance socks using Olefin as significant scale. Not only is Olefin extremely light and excellent at wicking moisture, it is also stain, mildew, perspiration, and abrasion-resistant.

Merino wool

Featured in our Pursuit and Flite XT Trail socks, Merino wool is much thinner than traditional wool, making it softer and wearable directly against the skin without causing irritation. It traps air efficiently, wards off odor-causing bacteria, and wicks away moisture, making it an optimal material year-round. 

NYLON

Nylon is a synthetic fiber that has a well-earned reputation for being one of the most durable materials available. Carefully optimizing the amount of nylon in our socks to match their intended use helps us walk the fine line of delivering a product that is both rugged and high-performing.

Our Pursuit line is constructed with RWS Merino wool. The Responsible Wool Standard (RWS) verifies animal welfare and land management requirements and tracks it from farm to final product.

RECYCLED POLYESTER

Recycled polyester is used in our Maxus socks, transforming recycled water bottles into high-performance fiber. This helps us keep waste out of landfills while still upholding the same technology, strength, and comfort we pride ourselves on. 

POLYESTER

Polyester is a high-volume fiber typically used to create a plush feel. Swiftwick uses structurally modi­fied derivatives of polyester in the Vision and Impression collections and for the proprietary GripDry™ blend to achieve various performance benefits.
