This purple pair (big kids size 6) was for my daughter, but had to go back because she found them too cumbersome to put on.  She has somewhat of a wide / thick foot - and she can just be a pill.  Maybe a larger size would have worked.  However, she tried on my 8.5 womens and didn't like them either.  I think she's just impatient.  None the less, sadly they went back.  My son tried the purple pair on (and mine), and loved them... just not in purple :-)  I ordered the red pair for him.  HE LOVES THEM!  Would recommend ordering up a half size (or more for kids, or wide feet).  Maybe worth noting - the sole on the purple "big kid" Howser Slipper we received did NOT look like the pictures here.  It looked just like the pictures of the Howser Womens.  A different "pattern", lower profile, and did not have the Keen imprint / logo on the side.  My son's red pair, looks just like the picture here, with the yellow keen logo on the sole (on the side and back).

I have this shoe in a women's 8.5.  They are very comfortable and feel great on your feet.  Great SHOE for running around, but these are not my idea of a "slipper".  Great for a casual shoe.  I would suggest ordering 1/2 size up, for better comfort, if you will wear socks, and for easier fit.  Otherwise true to size.  (I am normally an 8, and ordered an 8.5 in these... fit great and room for wool socks).  I would never ever wear these as slippers (1 star).  I will wear them as kicking around shoes (5 stars) for running errands.
