FALKE socks RU4 blue/gray

The FALKE RU4 blue/gray running and hiking socks offer medium cushioning and moisture control for men who want balanced protection and good contact in the shoe on every run or hike.

Fit and comfort

These socks use an anatomic left/right shape tailored to each foot, so they sit securely without creasing or slipping. Medium-strength padding around the foot reduces pressure points, which helps limit blister formation on longer sessions while still keeping a direct feel for the ground.

Materials and care

The RU4 construction combines 40% cotton, 40% polypropylene, and 20% polyamide. This cotton mix absorbs moisture quickly, while the synthetic fibers move sweat away and re-dry fast for a consistently dry feel on the skin. Machine wash them at 40°C on a gentle cycle, and avoid bleach, tumble drying, ironing, and dry cleaning to maintain shape and performance.

Performance features

The three-layer material design supports moisture regulation, moving sweat off the skin to help keep feet dry and comfortable. Targeted cushioning provides shock absorption where it is needed most, supporting endurance across road runs, trail outings, and light hiking.
