The Cush Booties were designed for camping, but I would definitely buy them for around the house because they have that one important selling point: they keep your feet warm.
Of course, if you’re planning to camp in cold weather you’re more interested in the specific features, so here they are. First, the outsoles are made from slip resistant nylon, so you won’t risk flying head first on a slick surface, but they’re still comfortable enough you can keep them on inside the sleeping bag. Second, they’re warm (the faux-shearling and nylon take care of that) and third, they don’t take up much space.
I’m not a camping pro in the least, but after freezing my ass (and feet) off in a couple of tents along the years… yes please, I’ll take all the insulation I can get.
