Side note, I like to keep ripped socks and use them for dusting the house, or as rags for cleaning.

I haven't field tested their mid-weight options in workboots over time, so no guarantees, but I know Duray is a Canadian brand and the winter weight pair I have has held up really well around the house and for snowshoeing.

I've also been looking for a Canadian Darn Tough alternative, but it feels like most of them are so bland, I wish there were some more options for good quality socks with personality!

I usually get my Darn Toughs from a local business so I felt okay about continuing to buy them, but the price has increased(as to be expected with tariffs, but they are already pricey to begin with) and they have discontinued the exchange/warranty program at that local shop, which definitely makes them less appealing.
