Review on 6 Pairs of CHARMKING Compression Socks for Women & Men - Best Graduated Athletic Support 15-20 mmHg for Running, Flight Travel, Pregnancy, Cycling - Boost Performance, Flexibility, and Durability (Multi 11, Size S/M) by Stephen Vasquez

These compression stockings do not have adequate compression. certainly not 15-20 as I have a pair of 15-20 and they fit a lot tighter, I have size 9 women's shoes and I bought size S/M. They should be snug, but they aren't! I'm disappointed! If you return them for any reason other than a defect, you will be charged a restocking fee! double whammy! UPDATE: The company accepted my return and credited my funds back to my account quickly, no restocking fees. That's good customer service. Glory!
