I love these: http://www.teamestrogen.com/products.asp?pID=26982
They have a 6 inch inseam so they aren't too long. They have a draw string on them, but once I tie it I don't think about it again. I have used these for up to 12 miles of running and 25 miles of biking with no chafing issues.
OH yea, and they aren't high waisted. They sit right on the waist or slightly below.
