I'm 145#, solid size 10 and size Large was perfect! I tried Medium but they were not as comfortable, almost binging in the groin area. The material is substantial enough and does not stretch out to the point of being see-thru like some I've seen at the gym (even the size Medium was OK in this regard)... The legs do ride up an inch or two during workouts, but are not binding or uncomfortable. Sweat wicks away right away, no clammy feeling. I'd recommend these w/o any reservations.
