What is an Unna boot?

As a compressive dressing, the Unna Boot is typically constructed from cotton and coated evenly with zinc oxide paste. An open wound or ulcer is a common place to utilize it for protection. Wearing a dressing that compresses your lower leg might increase blood flow to that area. In addition to reducing swelling and discomfort, compression helps. For many weeks, or until your wound heals completely, you may have to wear the boot. The Unna Boot’s zinc oxide paste not only keeps the region wet, but it also helps reduce skin irritation. Zinc is helpful for burns and ulcers because it speeds up the healing process at the location of the injury. Because it doesn’t set or cake, zinc oxide paste is better than alternative dressings that employ gelatin. You may get glycerin and calamine lotion at certain Unna Boots as well.

How to apply Unna boot?


The practitioner of medical treatment is the one who applies the boot.

  • Before applying the boot, raise your leg over your heart for 20 minutes. This reduces lower leg edema.
  • Your wound will be wrapped with petroleum jelly-soaked gauze.
  • Your doctor will bandage your leg from toes to knee. The first layer is gauze soaked with wound-healing medications and creams. Apply one or two layers of dry gauze. Elastic bandages may cover your leg.
  • As the footwear dries, it will become stiff. The boot’s snug fit will gradually give way to a more comfortable fit as you walk.
  • Every seven days, your Unna boot will be replaced. With each boot change, your wound will be cleansed and measured to ensure that it is healing properly.

Unna boot wrap & Unna boot dressing


An Unna boot is a special dressing of in-elastic gauze impregnated with zinc, glycerin, or calamine that becomes rigid when it dries. It is used to manage venous leg ulcers and lymphedema in individuals who are able to walk. The tight dressing limits the outward mobility of the calf muscle when the patient walks. This causes the contraction force to be directed inside, enhancing the pumping action of the calf muscle and boosting venous flow. An Unna boot lacks compressive properties and should not be used for patients with arterial insufficiency due to contraindications.

The Unna Boot is a hybrid wrap and dressing that goes from the back of the foot all the way up to the knee. The gauze of an Unna boot contains a specific medication that aids in the healing of burns or skin sores while also protecting newly formed skin. As a general rule, your healthcare professional may recommend changing the gauze bandage more often than once weekly. The Unna boot requires regular visits to the doctor or nurse for replacement.
