I enjoy the extra comfort and sweat wicking this sock provides under my prosthetic liner. I ordered one going by your measurements and it was too short. I called customer service and the gentleman I spoke with was super nice and sent me the next size up for free and it came very quickly. It was a little bit longer (like an inch) but STILL is a bit short for me. Not sure why that is. I would much prefer it to come over knee a bit higher where I'd have like 3" over top of knee. Being short (coming just over top of kneecap) , it tends to creep down slightly into the bend behind my knee. This is not comfortable for me. But the quality, softness,sweat wicking and seam are all outstanding. Perhaps I should still go longer?? I guess all of our limbs vary in shape souch that it's hard to fit everyone by one standard measurement.
