SorelMen's Dude Moc Mocassins

Can the insoles be washed? Either machine or handwash?

I presume the fake fur is not pure wool. If so is it polyester? Usually polyester makes me sweat and thus smelly feet. Do these get smelly?

How tight are these? I would normally buy a size 11 in a normal shoe.

Has anyone else noticed the seam is quite rough against the back of the heel? I have worn these for just a couple of days and already have a blister.
