Well, the rest of the dialogue is meaningless but: they are pretty sticky, galba comfortable wearing. They are more comfortable than compression socks that Madame is imposed on each flight and are well supported. From an aesthetic point of view, I can not say if I find her more beautiful legs with these tights with others, it would be so subjective anyway.
Rest scientific arguments on micro capsules of this and anti-that property. I am always very skeptical of such arguments and the absence of obvious observation through a serious and rigorous comparative study.
