You can see by the toe area that these clogs allow for more room (as many other clogs do too).  I prefer this as I can wear socks and have room..  Although when I go barefoot, they hold me in also. You have the optional strap that can swing over and be in back of the heel, (which will hold your foot snugly in place when walking), or have it swing back and be just decorative in the front (your foot will not slide out or have the feeling of unstability) if you chose the latter.  The clogs come with a white removable liner that can be wiped with a damp towel.  (I use a non alcohol wipe).  THESE were priced so very low I was skeptical at first. Now I have purchased more as I see that they are great for outdoor work also!  One can choose to put an insole inside for a custom fit that one cannot even find in a higher priced clog.
