Spenco Celine Slip-on Women's Casual Slip-on Shoe. Not all fashion sneakers are created equal. The Celine Slip-on is a step above the rest. Comfort and fashion are equally important, that is why we used perforated synthetic suede, soft synthetic calf linings, and a padded collar. The clean upper design is complimented by a simple rubber cup sole, making it your go-to fashion sneaker. Like all Spenco® Footwear, the Total Support® Footbed gives an unmatched level of comfort and support.
