Have you ever had a pair of Acorn Slippers? They are like heaven on earth! I particularly like this Dahlia slipper. They have a natural cotton/poly blend upper. They are fully padded and lined in soft berber terry. The nonslip, weatherproof outsole is perfect for inside or outside wear. They are machine washable and retail for $54.95. Check their website for information on where they can be purchased in your area.
Have at it!
