I decided to save $10per pair of Acorn slippers and buy them through Amazon instead of through the retail store I used to get them at simply because the price of these have increased dramatically in the past decade.  Boy, did I pay the price.  The new Acorn slippers arrived and had less padding under the foot than the pair I've worn daily for over a year.  I also had to cut some excess fabric away from the seams on the sides of the foot in both pair (yes, all four slippers needed trimmed).  The inconsistency in Acorn slippers is ridiculous.  When they fit right, they are a 5-star product.  When they don't...well 2 stars is adequate (or perhaps a bit high).  I've learned my lesson and will never buy another pair of these online.  I will pay the extra money at the bricks-n-mortar store where I can try them on to ensure sufficient padding under the foot and no excess fabric in the seams on the sides of the foot.
