The RU4 sock model is very comfortable thanks to its medium cushioning. This model offers balanced protection and good contact with the shoe. The cushioning also provides protection against blisters by reducing pressure points. Moisture transfer is quick and effective, allowing for both outdoor and indoor use in all sports activities. This model features a leg length that reaches up to mid-calf. These running socks made from breathable cotton and functional material feature a triple layer sole design to wick away moisture, which means your feet stay dry even during intensive running and sport. Whether it's on soft ground or hard tarmac — our versatile, medium padded sports socks offer cushioning and comfort, and the flat toe seam prevents pressure points, chafing and blisters. The sustainable material is robust and ensures high durability even with regular intense training; for a crease-free fit, we recommend the smaller size if you are in between sizes. Special knitting techniques adapted to the gender and anatomical differences of the right and left foot ensure a high comfort, a wrinkle-free fit, a long durability and protect against pressure points. This is a sustainably produced WE CARE item with a focus on environmental protection, animal welfare and social responsibility, tested for harmful substances and certified to Standard 100 OEKO-TEX.
