Question: How high is the lower shelf on the rack? Would I be able to fit a pair of sneakers underneath the bottom shelf?
Document: Nice shelf. I can store 9 pair of shoes in a very neat manner. Lower shelf is high enough to store shoes underneath. I liked it so well, I bought two more.
I bought this for my 12 yo son. He loves it. It keeps his shoes from cluttering his closet. He actually chose to place the rack against a wall in his room opposed to inside the closet. It shows well and is not an added eye sore. He has a ton of high top sneakers and they fit with ease.
Ended up purchasing this to put inside cabinet in our laundry room. Easily holds 8 pairs of children's shoes between the two shelves. We fit another 4 pair of sandals and lower profile shoes beneath the first rack.
Exactly what I was looking for. Easy to assembly and sturdy. I wear size 6 shoes and four pairs fit per shelf. Note the clearance on the lower shelf (8&#34;) and don't plan on putting the high-heeled ankle booties there. I'll buy more as space becomes available. Great purchase, great price.
I have size 10 shoes, but can fit 3 pairs of shoes comfortably on each tier. You may be able to get 4 pairs on each tier if you have smaller/thinner shoes, either small adult or childrens sizes. I have 4 pairs on the top shelf (the pairs I use the most), but I have one pair practically on top of the other pair.
Bought 2 for the bottom of the closet. They are spacious and sturdy and fit a good amount of clothes. I put shoes on the floor underneath. Very happy with these.
easy to put together and looks amazing in my closet. You could easily stack two/three pair of flip flops on top of each other (on the bottom shelf, not just the top). I haven't tried stacking any yet.
I don't really think these are decorative enough for indoors, but for our purpose - stacked two high and three wide in the garage they are invaluable.Having our garage door open directly in the living room means we have no closet or hallway for shoes. So just inside the garage we have a coat rack and six of these shoe racks. They stack nicely and look good side by side as well.They fit ALL our shoes from toddler to men's size 11.
This shelf is sturdy, looks good and is  perfect for my shoes - holds about 8 pair - wish I could fit two in my closet
I have 4 of these in a 2x2 arrangement to hold all of the shoes in the mud room closet. It can fit 4-5 pairs of women's shoes on a single shelf, but only 3 pair of large men's shoes. Overall, works great for my family's purposes and didn't give us any trouble setting up.
Answer: about 7 3/4 inches.  My sneakers fit
