These stockings were my winner's prize in a competition run - so that the sponsor has taken exactly the right thing for me, because I am passionate about them and carry them now almost always running or walking and cross-country skiing, I'll try it. Although they are tight, do not press; I have a very pleasant feeling when worn. They adapt well to foot and lower leg and are well padded in the right places; the comfort and fit are very good indeed. The material is high quality and well made; it is tested for harmful substances. Despite the relatively thin substance they keep nice and warm when I have cold feet; on the other hand they cool more and I sweat less when I have warmed myself. The specified in the product description optimal climate management is really noticeable. They hardly give off odor, much less than my other socks, even if I ran long. The fatigue sensation in the feet is only achieved later; and I have the impression that they help to regenerate, because their effect is almost like a massage. All these benefits have a little prejudiced in consequence: Since they are tight, they are hard on and take off, with the latter I use like the help of the traveling friends. Please note: The size of these socks is not to vote for the shoe size, but according to the calf circumference.
