Calf Compression Sleeves For Men & Women - Leg Compression Sleeve - Footless Compression Socks for Shin Splint &Varicose Vein

My calf is 15 inches, 5'9". I'm worried the medium will be too tight but the large too loose. Anyone else experience this? What size would be best?

My calf is 12" to 12.5". Should I got with small or medium? I am a nurse so I am on my feet twelve hours a day. Don't want them extremely tight

Are these good for flying?

I am thin and 5'5". My calves are 13 1/2" but I have very small ankles: 7 3/4". Would small or medium fit best?
