Outside budget but last several years so maybe worth it if you can stretch are the excellent Glerups slippers.

My pair are now 3 years old and still going! So comfortable in a wide range of temperatures too.

A GZ search on slippers brings up various options. My favorite slippers [Amazon.com] are about double your budget, plus shipping.

I looked last winter.
The better of all evils seemed to be kmart or farmers.
I looked at a few others but they started to get up to $80+

for $50 or less the farmers range is the better option.

Finch: Alright thanks. Didn't realise good quality slippers were so expensive!

Good quality usually is...!
