It is a pair of shoe protectors for pole dance. Universal size for different platform heights. Fabric tube goes to the platform of the shoe to take the beating instead of your expensive and sophisticated shoes. The sole remains open, so the clutch is still there and the tube is stretched, so it can be stretched to almost any size platform. Exotic shoe protectors will be damaged during use, but sox is better than our expensive precious shoes! We recommend using them on appropriate studio floors (laminate, wood, vinyl, etc.)
