The "Dimensions and Weights" description for this set of shoe shelves states that the width is 37 inches.  This is incorrect.  The outside to outside width is only 34 1/4 inches and inside the vertical supports is only 33 inches.  The shelving unit itself is well designed and strong enough to support the load of 40 pairs of shoes it can actually hold.  The 6 inch vertical separation between the shelves is adequate to handle my wife's and my shoes and small boots without having to twist them into place.  I will keep this unit, but if I had known the true dimensions of it, I would not have purchased it.  My 5-star rating reflects the quality of the unit, not Wayfair's (unfortunate and out-of-character) inaccurate description of it.
