The VACOcast Diabetic Boot provides the most comfort and stability out of all the VACO series. It is excellent for patients who want an all-in-one product option that does not also require a cast and walker. 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, ulcerations on the foot, Diabetic neuro-osteoarthropathy, DNOAP and Charcot foot, or post-operative care after toe amputations. Both the sole and liners are removable and washable for an easier time when cleaning. The large fits Men's shoe sizes 10.5 through 15 and Women's shoe sizes 11.5 through 14. Please note, if you are in between sizes, it is generally recommended that you choose the smaller size.
