These are a pair of Nike Calm Mule Slip on slides. Women size 9. Black slip-on lightweight molded construction with textured footbed. These minimalist shoes feature a seamless one piece foam construction designed for comfort and water friendly use. Made from soft but yet respinsible foam that is suitable for casual wear or beach outings. They are water resistant with a smooth matte finish and easy on-and-off style. Please note that the back straps are missing from these slides. This is why I have lowered the price.
