I’ve got some super cheap ones from Matalan, lovely. They’re not hut slippers, though, just big toasty furry boot things.
Thing is, I got hut slippers/camp shoes initially, because I didn’t want to admit that I wanted slippers. But they were just a gateway drug really- they were quite expensive for what they are, and they tend to have not much/no real sole, and a bunch of the budget goes on packability (and logos obviously) but that also tends to make them delicate. Most of that just makes them less good for around the house. Mine have enough (waterproof) sole to go and put the bins out or whatever, they’re bulky but it doesn’t matter, and they’re super warm, seem hardwearing and cost a tenner.
They do make me look slightly like the goon from popeye, though.
