Warm bootie that is also “presentable”? Thermoball mule, tent mule or something similar?

Hey all,
Looking to buy a warm, compressible down or synthetic insulated bootie that also – and you all will kill me – presentable around town. For example I am going to a Yellowstone camping spot, but also will be going out around small town, so something that is durable as well. I was contemplating the TNF thermoball mule – anyone have experience with that?
Thanks!
