I have very swollen feet with some disfigurement due to Rheumatoid Arthritis & diabetes. I cannot even wear 'regular' shoes anymore. I am female, size 10 shoe. I ordered mens' size 9-12 with extra wide crew. I was pleased with these socks, the quality & comfort. They are soft & more thick than thin. Good quality cotton. The crew size comes about halfway up your shin, stretches but does not bind. I wear socks to bed (pretty much 24/7) & these are really comfortable & non irritating to diabetic neuropathy. Warm enough but breathable. They wash well in washer. I recommend them highly.
