Im so pleased with these socks. I have trouble finding socks that don't leave indentions in my calves and ankles, and my legs aren't even that big! But no matter the length, all socks are too tight. But these... these are great. The roll top is the solution. But not all are created equal. Ive found some that still have a tight band under the roll - but not these. A true roll top, they fit my size 10 feet perfectly, and do not strangle my cankles.
