New liners for old Sorel boots

I got a pair of 25-30 year old Sorel boots, that I like a lot. The leather is great, Rubber Perfect, the soles got enough tread that I see no reason to replace the whole boot.

But the liners are worn out, I think I replaced the once 15 years ago or so. They are a thick wool(tag say 75% wool, 25% Acetate technically ). Does anybody know of a source(looking in the Canadian’s direction) for replacement Liner’s that will have the same thickness, and hopefully give a good fit, unlike some thin-ass Thinsulate or something, that will probably make my feet loose, slippy,and blistery.

Sorel sells replacement liners!

(My Huge Clompy Boots ™ are Sorels as well.)

That’s part of why they are so popular. I replaced the liners of my Sorels and then discovered that my feet had grown. Someone lucked out with my old Sorels and new liners because I donated them.
