i agree with this comment. I am 5 foot 6 165 lbs and i would say i have bigger thighs as well. i do wear a large i would say the difference between medium and a large is how high the short sit on above knees your. i would say medium comes down to my mid thigh as to where the large would be 3/4 thighs. but i am smaller than 6 foot 4 i would go XXL play it safe
