I know that you guys have all experienced this,actually I am. I have a big thigh, and have almost given up the idea of looking for thigh high socks because they always stay on my knees.
Some thin thigh high socks can't even exceed my knees. It is suspected that they may be prepared for kids. I can hardly imagine that an adult fit them. Just few thigh high socks perform better, but they are still not enough for my thick thighs.
People who have the thin thighs would not think that some thigh high socks will cut off circulation. The top spandex of those socks is narrow, just about one inch, so these socks will cut deeply into your thighs and leave a deep trace. We are looking forward to a pair of thigh high socks with a wide top band. This is a good design to protected.thick thighs.
Until I found Kayhoma thigh high socks. When I took them of the bag they looked tiny and I did not expect them to fit but they stretch to fit your legs. Somehow these fit perfectly. These might easily be my favorite thigh highs I currently own. They are so soft and warm, fit my thick thighs very well, still look & feel brand new after several washes.
