Lululemon's Run Inspire Crop II. It has a draw-string but more importantly, a medium-rise waist (as opposed to low-rise), which, I think is key. They are really expensive, but worth it. The fabric really holds up well over time - no problem with machine wash and dry.

Drawstring. Hard to find, but very worth it. Can't remember what brand mine are, so look around.

I did also just buy a few pairs of capri leggings from Target and am pleasantly surprised at how well they stay up, even without the drawstring.

I have a pair of Reebok ones I got on sale at Dicks. Haven't had a problem with them, but I use them for general cross training and classes. Usually only run for about 30 minutes.

I have a pair from athleta I really like. So far they are staying in place just fine (but I don't run for more than 40 min at a time)>

+1 for Nike. Also, just bought a cheapie pair from Old Navy and was surprised how much I liked them.

I have a pair, Nike brand, that really stay up. Unfortunately, I'm not sure of the specific style name.

I am looking for the best running pant that DOES NOT ROLL DOWN WHEN RUNNING. I hate having to constantly tug at them when the start tugging downward. I have bought so many --even many of the compression type that claim to really squeeze you -- and inevitably they fall down to. Do you have any that you love that stay put even on long runs.

Thanks so much!!!!
