The concept is great and if it worked right it would increase storage capacity by 100 percent. Nevertheless, I have a few suggestions for the designer: Due to the design, high heels or wedges are not suitable. It only lifts one side of the platform - this allows the shoe to fall further. (A better design would be to adjust the back of the device to the height of the heel). Also, the heel stopper is too short, which allows the shoe to fall off the platform - and it keeps coming out of the groove. In my opinion it should have been made higher and permanently fixed. Last but not least, there are cleats on the platform, but the molded plastic doesn't allow the shoe to hold up well. The best design (again in my opinion) is deeper grooves or material that provides more friction between the pad and the block.
