Hi, am walking from May 11 from sjpdp, have been training with long walks and have really painful varicose vein pain in my calves when I walk over an hour. I bought some 2xu compression socks to try but they didn't help much, today I walked 3 1/2 hours and was in agony and was wearing the compressions socks. Is there another compression sock that someone has used that they would recommend ? Any advise would be so appreciated as it seems hard to find advise for this issue! Thanks
