I have pronated feet (hello bunions) and we have hardwood floors throughout our entire house. Thank goodness for these slippers! I previously bought the 'summer style' Orthaheel slipper (my term - they just have open toes at the top) and now these. I can be in my slippers all day if I want and my feet are happy because they offer great support for my arches compensate for my pronation. They also have a velcro strap to adjust for tightness on the top.  I highly recommend them.
