This shoe rack is made of a thickened metal frame, wire grid, and adjustable feet, ensuring reliable stability. It can hold up to 30 lb for each shelf, with additional bottom storage for more shoes. The 4-tier shoe rack can store up to 12-16 pairs of shoes. The inclination of the shoe organizer rack can be adjusted to level or tilt according to your usage habits. Behind the shelf is a baffle to prevent shoes from falling. The shoe rack is stackable, and 2 sets or more can be stacked vertically for a complete 12-tier shoe rack to make the most of small spaces in the closet, entryway, and corners.
