I don't like "running" shorts because they are too short, the waist is too tight, and I hate the liners. I have large thighs compared to my waist. The smallest part of my waist is really, really high, so elastic bands on running shorts tend to ride up to that part which makes me look like a dork. I like lower rise shorts that won't pinch and will fit my legs. Not easy to find. I have two pairs of general workout shorts I wear running, my old Nike dri fit shorts, which on their way out because they are old and worn. My other pair are new and I love them so much I'm getting a second pair: http://www.landsend.com/pp/Performan...62448428175932 (I think I must wear mine a little lower than the model does, or maybe she just has really long legs, they don't look that short on me). I saw the picture of these and thought they would work for me because they have a smaller waist that doesn't pinch and large leg openings. Bingo! They fit me perfectly. I wear my regular cotton underwear with them. They don't ride up or chaffe, but I only run about 3 miles at a time. I'm working on increasing my distance and don't anticipate any problems. My favorite thing about them is a zippered MP3 pocket that fits my nanopod pefectly, also has a key pocket on the outside.
The best part about going up hills is riding back down!
