Phase Socks - Carbon

£18.00

Carbon technical rib knit socks engineered for runners who demand performance without compromise. The advanced knit construction delivers targeted cushioning precisely where your foot needs it most, reducing impact and fatigue during every stride.

The low-profile arch band provides essential support that moves with your foot, maintaining stability without bulk or discomfort. This thoughtful design keeps your focus on your run, not your socks.

Built for distance, built for speed, built for the runner ready to push through challenging conditions. These socks transform what happens beneath your shoes into a genuine advantage on the road or trail.

Sizing

Find your starting size in the NADIR Size Guide. For tops, measure your chest or bust; for bottoms, measure your natural waist. Choose socks by UK shoe size and gloves by hand circumference. If you’re between clothing sizes, choose the smaller size for a closer fit or the larger size for more room.

For technical apparel, wash inside out with similar colours on a cool, gentle cycle. Avoid bleach and fabric softener, then air dry away from direct heat.

For accessories and outerwear, check the product label before washing, as care needs may differ.
