My regular size is 9.5, so I bought size 9, and they fit perfectly.  They are excellent.  Very comfortable.  I wear them in the shower every day and it provides such relief to my feet compared to standing on the hard tile floor of the shower (I have plantar fasciitis).  The toe piece is fabric but it seems to be sort of water repellant because it dries quickly afterwards.  I bought the brown leopard sandals.
