I bought these when I was looking for colder-weather running pants. On the plus side, the fabric of these is nice and soft (though it does make a "swishing" sound, which does not bother me but may be a consideration for some), and I found the length to be adequate: I'm 5' 10", and these pants reached down past my ankles so they just hit the floor. However, the fit around the middle of these was very small on me: I usually wear a 12 or 14, and the XL was really tight around my thighs and rear -- way too tight to be comfortable for exercising. I wound up returning them for that reason.

If you have a skinny lower half then these will probably fit you okay, but I'd still recommend going a size over your usual just to be on the safe side.
