I have somewhat skinny calves and was concerned about finding something tight enough to improve my circulation or missing something. They stay tight even after multiple washes (although I do let mine air dry). I liked them so much I bought a pair for my fiance because he split his shins while running and jumping rope in CrossFit. He wore them continuously for two or three weeks and his shin splints healed and did not come back for several months.
