Hi Emily, Have u tried ECCO sandals? I too have low volume feet and i have been wearing their sandals for years. I wear them all the time, and i'm currently wearing the black Odense sandals. the leather is so soft and comfortable. they also have models with thicker sole for more walking perhaps, but they are really worth every penny. I googled ECCO Sandals and the zappos page came up. Good luck with you sandal search, I'm tempted to buy another pair of the Odense ones because I really do like them and it's usually a year or 2 before the next season comes around where I see something I like.
