Diabetic Foot Ulcer Treatment: What to Do and How Offloading Helps
A diabetic foot ulcer—often shortened to "diabetic ulcer" when the wound is on the foot—is an open sore that requires prompt medical assessment. Diabetes-related nerve damage can hide pain, while reduced circulation can slow healing. Treatment commonly combines wound care, pressure offloading, infection and circulation assessment, diabetes management, and close follow-up.
The products in this collection are clinician-directed removable offloading devices designed to reduce pressure on selected plantar (bottom-of-foot) wounds. They do not diagnose an ulcer, replace wound care, treat infection, or restore blood flow.
What Is a Diabetic Foot Ulcer?
A diabetic foot ulcer is a break in the skin of the foot in a person with diabetes. It often develops where repeated pressure or friction acts on tissue that has reduced protective sensation. Diabetic neuropathy may make a wound painless, and peripheral artery disease may reduce the blood flow needed for healing.
Early signs may be easy to miss
- A blister, crack, cut, or open sore
- Drainage or staining inside a sock or shoe
- A callus with bleeding or dark tissue underneath
- New redness, warmth, swelling, or odor
- A change in foot color, temperature, or shape
Common clinical terms
- Plantar: on the sole or bottom of the foot
- Neuropathy: nerve damage that can reduce sensation
- Ischemia: inadequate blood flow to tissue
- Offloading: reducing mechanical pressure and stress at the wound
How Is a Diabetic Foot Ulcer Treated?
There is no safe one-product or at-home cure. A clinician should examine the wound and create a plan based on its depth and location, sensation, circulation, infection status, foot shape, and overall health. A diabetic foot ulcer treatment plan may include:
- Wound assessment and classification: measuring depth and tissue involvement and checking for infection, reduced blood flow, neuropathy, and Charcot changes.
- Professional wound care: cleaning, appropriate dressings, and debridement when indicated.
- Infection treatment when infection is diagnosed: antibiotics do not replace wound care or offloading and are not automatically appropriate for every ulcer.
- Circulation treatment: vascular testing and treatment may be needed when blood flow is reduced.
- Pressure offloading: a cast, walker, shoe, orthosis, or other modification selected for the wound and the person.
- Whole-person care: diabetes management, nutrition, smoking cessation when relevant, and scheduled reassessment.
A wound that is not improving as expected needs reassessment; the care team may need to change the offloading plan, investigate infection or poor circulation, or use another treatment.
Why Offloading Matters in Diabetic Foot Ulcer Care
Standing and walking repeatedly load the bottom of the foot. Offloading reduces mechanical stress at the ulcer so the wound-care plan has a better chance to work. The IWGDF offloading guideline identifies a non-removable knee-high device as the first choice for many neuropathic plantar forefoot or midfoot ulcers. When that option is contraindicated or not tolerated, a clinician may consider a removable knee-high or ankle-high device.
This distinction matters: a removable diabetic shoe or walking boot is not automatically the best device for every diabetic ulcer. Infection, ischemia, wound location, balance, fall risk, leg-length difference, skin condition, and ability to use the device as directed can change the recommendation. Do not remove insole plugs, alter padding, or begin weight-bearing without instructions from the clinician managing the wound.
Compare Diabetic Ulcer Offloading Shoes and Walking Boots
These two Össur devices provide different levels of coverage and access. This comparison is for product education; your wound-care clinician or podiatrist should select, fit, and modify the device.
| Product | Device format | Product features | Discuss with your clinician |
|---|---|---|---|
| Össur DH Diabetic Offloading Post-Op Shoe | Lower-profile, post-op-style removable shoe; fits the right or left foot. | Modular insole plugs can be removed by a clinician to create targeted relief beneath a selected plantar wound; designed to accommodate dressings. | Wound location, plug-removal pattern, dressing bulk, fit, stability, and whether an ankle-high device provides sufficient offloading. |
| Össur Rebound Diabetic Walker | Taller removable walking boot with lower-leg and ankle coverage; fits the right or left side. | Tri-laminate pressure-relief insole, rocker sole, access portals, Flex Edge® construction, and tamper-evident straps. | Whether a knee-high removable walker is appropriate, safe weight-bearing limits, liner and strap setup, skin monitoring, and balance. Contains latex; do not use with a known latex allergy. |

Diabetic Foot Ulcer Infection and Circulation Warning Signs
Because neuropathy can reduce pain, the appearance, smell, drainage, color, and temperature of the foot may be more noticeable than discomfort. Contact the treating clinician promptly for any new or worsening wound.
Get urgent medical help for
- Spreading redness, warmth, or swelling
- Pus, increasing drainage, or a strong odor
- Fever, chills, weakness, or confusion
- Rapid wound enlargement or exposed deeper tissue
- Black, blue, gray, or dying-looking tissue
Also report immediately
- A foot that becomes cold, pale, blue, or much darker
- New rest pain or sudden severe pain
- A hot, red, swollen foot or sudden shape change
- A device that causes rubbing, pressure, numbness, or skin injury
- A wound that is not progressing as the care team expected
Daily Foot Protection During and After Treatment
- Inspect the tops, soles, heels, and spaces between toes every day; use a mirror or ask for help if needed.
- Keep dressings and offloading devices clean and dry as directed by the care team.
- Never walk barefoot, and check shoes for seams, stones, or other pressure points before putting them on.
- Do not cut calluses, drain blisters, use medicated corn removers, or place heating pads on a foot with reduced sensation.
- Follow the prescribed device schedule and activity limits. After the ulcer closes, continue preventive foot care and clinician-recommended footwear.
Diabetic Foot Ulcer Frequently Asked Questions
What is a diabetic foot ulcer?
A diabetic foot ulcer is an open sore or break in the skin of the foot in a person with diabetes. Neuropathy can reduce pain and protective sensation, while poor circulation can slow healing and raise the risk of complications.
What is the best treatment for a diabetic foot ulcer?
The best treatment is an individualized plan from a qualified clinician. It commonly includes wound care, pressure offloading, assessment and treatment of infection or reduced blood flow when present, diabetes management, and regular follow-up. No shoe or boot is a complete treatment by itself.
Can a diabetic foot ulcer heal on its own?
Do not wait to see whether it heals on its own. Even a small or painless diabetic foot sore can worsen because neuropathy may mask damage and reduced circulation may delay healing. Arrange prompt evaluation by a doctor, podiatrist, or wound-care clinic.
Can I walk with a diabetic foot ulcer?
Only follow the weight-bearing and activity instructions set by your treating clinician. If a removable offloading device is prescribed, use it for weight-bearing exactly as directed. Walking without the prescribed protection can repeatedly reload the wound.
How long does it take for a diabetic foot ulcer to heal?
There is no universal healing time. It depends on wound depth and location, infection, circulation, glucose management, pressure relief, and other health factors. The care team should track wound progress and reassess the plan if healing stalls.
What are the stages of a diabetic foot ulcer?
Clinicians use classification systems to describe depth, infection, circulation, and amputation risk, but these are not reliable self-assessment tools. A photo or wound size alone cannot show the full severity; professional examination and circulation testing may be needed.
What is the difference between the Össur DH shoe and the Rebound Diabetic Walker?
The DH is a lower-profile post-op-style shoe with a modular insole for clinician-directed, site-specific plantar relief. The Rebound is a taller removable walker with lower-leg support, a pressure-relief insole, access portals, and tamper-evident straps. Neither is simply a mild or severe option; the correct device depends on the wound and clinical assessment.
When is a diabetic foot ulcer an emergency?
Seek urgent or emergency care for fever, chills, confusion, rapidly spreading redness or swelling, pus or a strong odor, black or blue tissue, a suddenly cold or pale foot, severe new pain, or a hot, red, swollen foot. These may signal infection, impaired blood flow, tissue death, or Charcot foot.
