Worn maybe two times, just didn’t work for me. I do not have the optional inserts that come with them anymore. Canvas with air holes, this is a great summer sneaker and looks cute with dresses, Even though it is a sneaker. Please see the pictures and ask any question. We are a dog friendly house, he may not wear the shoes, but his hair can be sneaky. Please note that these have a rubber smell when they are new. My husband wears his often and the smell is gone, but since these have not been worn much, It is still noticeable.
