it is true that tights can help prevent vericose veins but then,
i thought guys wore long johns.
Yes, pantyhose with support legs, eg. Futoru with compression legs
of 18/21 mmHg provides support for legs to relieve leg
fatigue/aching and also prevent vericose/spider veins. You
can find a lot of info on vericose veins and their preventive
measures on the web. THere are a lot of pantyhose with
support legs in the stores, and for preventive measures, they are
sufficient.
Long johns are for cold weather, Quinsy. Long johns do not
provide the support needed. If I do go to cold weather,
opaque pantyhoses are more comfortable than long johns (pricky when
you go into places with heaters, very uncomfortable).
