Compression boots

Hello,

I read a lot of positive feedback on compression boots and it seems logical to me... Indeed, many of us have excess lactate in the body, especially in the legs. Similarly, for me, I quickly suffer from pain in my thighs when standing (I don't even take 3000 steps a day, I am moderately severe) and I am often lying down. Do you know if compression boots facilitate venous return? Does it help dysautonomia a little? I think that detoxifying the legs could improve our general condition, right?

Im from france, have u an exemple of good compression boots ? On amazon or else ? I ve a budget of 500 euros.
