I bought this to put away my summer sandals in a spare closet.  Works great.  The slots are wide and deep so even if the shoe has a heel, it still fits and the shoes can be stacked or side by side.  I would not recommend for heavier type shoes since it's held onto the closet bar by a nice-sized velcro wrap.

I would recommend airing it out in a garage or outdoors if possible as the fabric has an industrial kind of odor to it that you don't necessarily want in your closet. 

Pros: great value, versatile, size
Cons: tad bit smelly
