Diabetic shoes are a specific class of protective footwear engineered to prevent injury and complications in individuals managing diabetes. Unlike standard footwear, these specialized shoes are designed to accommodate and mitigate the unique risks diabetes poses to the feet, particularly concerning skin breakdown and pressure points. Wearing these therapeutic shoes is considered a standard of preventative care to maintain foot health and mobility.
Understanding Diabetic Foot Complications
The need for specialized footwear stems from common diabetes-related conditions that compromise the feet’s natural defenses. A primary concern is peripheral neuropathy, which is nerve damage leading to a loss of protective sensation, meaning a person may not feel blisters, cuts, or foreign objects inside their shoe. This lack of pain awareness allows minor injuries to escalate into serious wounds without the person realizing it. Additionally, diabetes can cause peripheral arterial disease, which restricts blood flow and oxygen to the feet.
Poor circulation hinders the body’s ability to heal and fight off infection. These unhealed wounds often develop into diabetic foot ulcers, which are responsible for approximately 85% of lower extremity amputations in people with diabetes. The lifetime risk of developing a foot ulcer is estimated to be between 19% and 34%. Foot deformities, such as bunions or hammertoes, further compound the risk by creating areas of abnormal pressure prone to ulceration.
Specialized Design Elements
Diabetic footwear incorporates several engineering features that differentiate it from regular shoes, all aimed at reducing pressure and preventing friction. A defining feature is the extra depth, which provides additional vertical space, typically one-quarter to one-half inch deeper than conventional shoes. This depth is necessary to comfortably house custom-molded orthotic inserts, which are designed to evenly redistribute plantar pressure and cushion the foot.
The interior uses a seamless or smooth lining, often made of soft materials, to eliminate abrasive contact points and stitching that could cause irritation or blisters. The toe box is generally wider and deeper, ensuring toes have ample room and are not compressed. Many therapeutic shoes also incorporate a rocker bottom sole, a curved design that reduces the range of motion required at the ankle and forefoot during walking. This sole minimizes pressure on the metatarsal heads, common sites for ulcer formation, by facilitating a smoother roll-off motion. The shoes also come in multiple widths to ensure a precise, non-binding fit that accommodates swelling or structural changes.
Categories of Diabetic Footwear
Prescribed diabetic footwear is generally categorized based on the level of protection and accommodation needed. The most common category is the extra-depth shoe, also known as therapeutic footwear, which is suitable for daily wear and accommodates custom orthotic inserts. These shoes are often available in styles resembling athletic shoes or loafers, providing preventative protection for individuals with loss of sensation or minor foot deformities.
Custom-made shoes represent a higher level of intervention and are constructed from a cast or mold of the individual’s foot. They are typically reserved for patients with severe foot deformities, such as those caused by Charcot foot, when off-the-shelf options cannot provide adequate pressure relief. A separate category includes healing or post-operative shoes, which are temporary devices worn after surgery or during the treatment of an active foot ulcer. These devices, which can be open- or closed-toe, are engineered for maximum off-loading, meaning they completely remove pressure from the wounded area to allow for healing.
Obtaining Prescribed Footwear
Acquiring specialized diabetic shoes requires a formal medical process to ensure the footwear is appropriate and covered by insurance. The first step involves obtaining a written prescription and certification of need from the doctor managing the patient’s diabetes. This certification must confirm that the patient has diabetes and a qualifying foot condition, like a prior foot ulceration or significant neuropathy.
The prescription is then filled by a qualified professional, such as a podiatrist, orthotist, or pedorthist, who is responsible for fitting the shoes and inserts. Proper fitting is paramount, as an ill-fitting therapeutic shoe can negate its protective benefits. Medicare Part B often covers one pair of extra-depth or custom-molded shoes and three pairs of custom-molded inserts annually, provided the patient meets the specified criteria. Patients should always confirm coverage details with their insurance provider, as deductibles and co-insurance amounts may apply.
