Excellent socks, but the sizing needs special attention

They are of high quality both in materials and in the processing and provide good stability for muscles and joints and improve blood circulation.
They are slightly thinner than my other compression socks, but support my opinion anyway as well; but are not so hot, so I will certainly put in the warmer months, rather than my other 'and now in winter I can pull over a little warmer. Also at the bottom they are thinner than my other and thereby bolster there less' but the better my athletic shoes have been doing this enough.
This is a sporty compression stocking, but certainly not a medical support stocking; therefore particularly suitable for sports, but in the absence of medical support stockings I get rid of this sport even when special trips such as long-haul wear.
But now to the issue of size determination: I have shoe size 41, would have to take to the table given here Size M; but I have relatively thick lower legs and have therefore taken L 'I repented not. Because due to the experience of purchasing my other compression socks in specialist shops under the advice and measurement of lower leg circumference I am of the opinion that the lower leg circumference is more important than the shoe size; I let me also confirmed by the expert that this Zensah compress the lower leg just right 'for the front of the foot do less, but still sit well, so not wrinkle or otherwise obstruct; this really only applies to the forefront at the foot, otherwise they compress the foot well.
My wife has this Zensah socks; she has shoe size 37, size S taken accordingly, does not get any smaller. But she's right lower leg thin 'and we have the impression that they compress there not quite as good, but better on the foot.
Both me and my wife shake socks (in each size) just below the knee 'what we consider to be optimal.
We would like to add that on and off is much harder than in non-compression stockings; when I'm exhausted right after a big sporting activity, I let me undress these stockings but very happy by helping others.
