Performance Fiber
Our performance fiber creates a lightweight close-fitting sock designed for breathability and durability, with properties such as moisture wicking and adaptive warming and cooling.
Many of our sock silhouettes are engineered with a unique mesh design, providing a thin, light, cool feel for warm days and close-fitting shoes. We use nylon to reinforce the heel and toe zones, lycra for a compressive fit, and locally-manufactured recycled fiber, reducing landfill waste.
