These things are super thin. They have no structure unlike the product image, which implies that they at least look like shoes. They're just cloth bags for your feet. The outsole looks like a nerf and I don't expect it to last more than a month or two. If they last longer than three months I'll edit this review, if not I'll let it stand. EDIT: It's been over five months, they've held up very well! They are comfortable and I wear them often.
