I PURCHASED GRIP6 CREW SOCKS [LARGE] FROM YOU ABOUT 3 MONTHS AGO, AS I WEAR SIZE 11 SHOES. I FOUND THAT THE TOP BAND OF THE SOCKS PRODUCED A SIGNIFICANT DEPRESSION BY THE END OF THE DAY, WHICH LEFT MY FEET AND ANKLES CONSIDERABLY SWOLLEN. BY MORNING, THE SWELLING IS GONE. THEN, WHEN YOU HAD A SALE FOR FACTORY SECONDS, I OPTED TO PURCHASE SIZE XL. THE SAME THING HAS OCCURRED AND I CANNOT WEAR THESE EITHER. I AM A RETIRED DOCTOR AND KNOW THAT I DO NOT HAVE DIABETES NOR CONGESTIVE HEART FAILURE CAUSING LOWER EXTREMITY EDEMA. WHAT DO YOU SAY? DR. RICHARD DeMARK
