I am not a skinny little marathon runner. I usually wear a large in shorts. These run big, so they make me feel a little skinny! :-) They have a backup drawstring, so I can't decide if I should return them and get the medium. I am older and little shorts on older ladies is a fashion no-no...just my opinion.
These are amazing shorts! The stretchy wide waistband is so comfortable and the inner draw cord helps them stay put. The waist also hits at a perfect spot if you don't have a perfectly flat stomach. The material is very light and breathes very well. I also appreciate the 4" inseam I hate tugging down my shorts when I'm running. These shorts do seem to run slightly large; my old Adidas shorts are mediums and the small fit perfectly in these shorts (5'6" 138,lbs, 35" hips 27 1/4 " natural waist). It's not in the description but it's nice to note that these have an inner brief. Hope they make these in more colors!!
i saw these shorts while in Boston in April for the marathon and almost bought them. I decided not to and wished I did. I wound up ordering them online and was so glad I did...and they were on sale:). I am 5'3" and about 130 pounds and a small is roomy but not too big.
