Pictures: Tan sock is S/M and Blue sock is L/XL Ordered these for my friend who, after ankle surgery, has an atrophied calf that is much smaller. His shoe size placed him in L/XL and his calf S/M. We ordered both sizes to compare, and figured he would take the S/M and I’d take the L/XL. Due to his lack of flexibility and patience, he couldn’t get either size on! So much for that. I was able to get both sizes on though. My measurements: Women’s 10.5 US shoe Inseam: 34” Calves at widest: 16.75” Calves just below knee: 14.75” I was able to get both sizes on without great struggle (flexibility does help and I rolled/put them on like you would hosiery or stockings). Both sock toes and heels were where they should be. Both socks pulled all the way up to just below the knee. Both were quite snug in the toe box, with the S/M fitting tighter (but not too tight to wear all day). I was able to get the S/M over the widest part of my calf, although the elastic band was tighter just below the knee than I would prefer. I think after a full day that level of tightness would be irritating. Ultimately, I would be able to wear the S/M if needed, but the L/XL are more comfortable and still offer noticeable compression. The fabric felt good and I look forward to trying these out after the gym to se if they help alleviate a chronic calf knot I deal with. BOTTOM LINE: If you are between sizes, I suggest basing your final decision on your calf measurement and not your shoe size.
