I've always played well other brands a chance. But had to realize again and again that the "booties" have constantly rolled down while running, or that after a short use already the stuff was getting thinner and it was only a matter of time before showing the first holes. That's why I always come back to the PUMA socks. From the foot size I am, unfortunately, exactly between the sizes 39-42 and 43-46. Can anyway both versions carry easily without slipping of the socks actually. Even the colors are retained even after frequent wearing and repeated washing broadly.
