Household Essentials Cedar Fresh Boot Shapers protect your footwear investment by keeping every boot in ideal strutting shape. You get four shapers to support 2 pairs of boots. These sturdy, flexible plastic shapers roll and fit inside ankle, calf, and knee-boots. They measure 17.2 inches high, 10 inches wide, and 0.1 inches deep. Each shaper can be trimmed using pre-marked lines to customize their fit to short, medium, or tall boots. Once trimmed, shaped, and inserted, they unroll to perfectly imitate the original form of the boot. This keeps boot legs and ankles straight, which keeps your boots looking like new longer. Prevent cracks and creases while also increasing ventilation throughout the boot for fresher footwear and better boot care. Shapers adjust to the shape and size of your boot, so each boot receives custom attention: simply choose a size, curve to shape, and slip shaper into the boot. The shaper will automatically adjust to fit your boot. The built-in loop makes it easy to remove the shaper. The loop can also double as a hanger to hang boots on shoe trees for quick storage. It’s an inexpensive way to keep your boots in better shape.
