This shoe rack does not hold 50 pairs. It will hold 30 pairs of men's shoes, or 40 pairs of women's, no more.
Also the tiers are spaced so close together that men's shoes must be placed on the rack from the back. They will not fit in from the front. As a result, either the rack must be turned around each time a pair of shoes is stored or removed, or it must be kept with the backs of the shoes facing out.
Finally, it is flimsy. Each of the diagonal supports on the ends (which the cross bars attach to) is attached only by a small tack weld at each end.
The design concept of this rack is good enough that were it large enough and better constructed, it would likely be a good product. As it is, it is not at all worth the "retail" price, and really not even a good value at the sale (under forty dollars) price.
