text: They are a cozy slipper but I wish I would have read more reviews about sizing up. I have 5 pairs of ACORN slippers and this is the size I always order (8/9). They run small and my toes are sore after wearing for just a short time. If you order then definitely order a size up. Would have given 5 stars if it said in item description to order a size up from your regular size in the ACORN slippers.
