This is about the 5th pair of these shoes I have ordered for my husband.  He had to have his Achilles tendon reattached two years ago and the heel area is very sensitive.  He loves these shoes as house slippers and his every day shoes.  They fit perfectly and do not rub the sensitive area and feel good on his feet.  He is very picky !  He wears a size 12 and they have always fit exactly right.
