Have worn Acorn slippers for years; they last and last!  Comfy, sturdy, warm and easy to wash.  We've noticed the fit has gotten a little smaller, now that they are made in China.  Two things we would like--better sizing, a slightly narrower fit or sized in narrow and wide, as well as, individual sizes, not multi-sized AND even though they are cushioned, more would be better, with a little arch support.  We like the tex moc and polar moc styles, the best.  Don't ever want to be without them!  We love them!
