"This is probably the only comfortable shoe I've worn by Bandolino. I wear size 5.5 in flats and heels and these fit perfectly. I love the ballet square toe look and these give you plenty of toe room. The slight heel dresses this up enough to wear to work or casually. The material is seems to be nylon with a soft finish. My only issue is that this material tends to attract a lot of dust and pet hair."
