There was another post about this awhile ago and as I stated then if you have BAD varicous viens as I do from years of working 14 hour days on my feet then the socks help both in recovery and even while riding, your legs will feel less heavy and there will be less dull ache and also less leg cramping [the calf]. These socks need to be fitted for the best outcome and they are not cheap a good brand is Sigvarius from Germany. If you have no vien problems then I have no idea if they help, as I speak from the point of view of a vien suffer.
