Neu HomeOrganize It All 9-Pair Freestanding Shoe Rack

I have been hunting for a narrower (width-wise) shoe rack that will hold 4-6 pairs. Can I put this together without a 3rd row?

Can you use this for booties?

Can this shoe rack's materials good for outdoor

Is it possible to cut-down the width by taking off 2 shoe holders to reduce it to 6 holders? Or can someone show a close-up of how the sides connect?
