When in doubt, go with a clothing item that looks presentable for work but feels like wearing sweatpants. I don't know how long this faux-track pant look will last (probably not long) but I plan on milking it for all that it's worth. The only downside is that you are pretty much required to wear these pants with heels if you don't want to risk looking like a complete slob. (If you see examples to the contrary, please send them my way!) Heels really just make everything worse.
Have a great Wednesday.
