The VACOped Diabetic Boot is clinically proven to be the best choice for offloading difficult heel ulcers. The built-in range of motion allows the user to adjust the boot to 10 degrees dorsal flexion to shift weight forwards and off the heel when needed. It features vacuum technology for successful wound healing due to pressure relief. Bead-filled inserts act as a vacuum cushion as it molds to the user's foot like plaster casting to offload heel ulcers. It then re-molds per each fitting allowing for easy wound inspection. Simplifying treatments for medical professionals. The toe of the boot is covered to protect neuropathic feet from debris entering the boot. The rocker sole gives better pressure distribution. With the additional foam insole for added shock absorption and additional offloading. The low friction wicking synthetic velour liner is also gentler compared to regular treatment boots. Perfect for patients who have any indications of diabetes such as Diabetic Foot Syndrome and heel ulcers. Both the sole and liners are removable and washable for an easier time when cleaning. The small fits Men's shoe sizes 2.5 through 5.5 and Women's shoe sizes 4.5 through 8. Please note, if you are in between sizes, it is generally recommended that you choose the smaller size.
