Falke RU4 is a supreme running sock without seams. The sock is divided into left and right and has an excellent fit. The sock is made with a heavier and more durable fiber at the heel and toe. This makes the sock very comfortable. Ventilation channels have been weaved in at the instep and under the foot, which makes it extra moisture transporting. The sock has a thin top. Yet, because of the comfortable part at the heel and toe, the sock still takes up a bit of space in the shoe. The sock can be used most of the year, but it is best suited for when it is warm.
