In order to fit boots on a shoe rack, you will need one that has at least one shelf that has ample space between it and the one above it. However, you aren’t limited to one type of design as you shop. Some vertical and horizontal designs offer compartments of various sizes as well as adjustable shelves. You can place boots on the top tier of shorter horizontal racks. Keep in mind that most shoe racks that fit over a door do not have enough space to fit tall boots.
