Foot Insole treatment for Diabetic Foot Ulcers


New shoe insole could treat diabetic foot ulcers

Purdue engineers are designing shoe insoles that could help heal diabetic ulcers.

14-24% of US diabetics develop ulcers that can lead to loss of toes, a foot, or leg.

Diabetic ulcers commonly result from high blood sugar damaging nerves, which takes away feeling from the toes or feet.

Traditional treatment for foot ulcers is a total contact cast and hyperbaric therapy.


The goal of this new insole is to increase mobility and heal wounds.


The Design is made from an image of a patient’s wound.

Laser machining creates a custom silicone-based insole of each patient.



A Special reservoir delivers oxygen directly to the wound throughout the day.

A little bit about Feet and Leg Problems with Diabetes / Diabetic Feet

People with diabetes have unique issues with their feet.

Everyone’s heard the horror stories about people they know with diabetes or friends of friends who end up losing toes or losing feet losing their legs.

Most of that is really preventable.

The reason that those sort of things happens isn’t that of diabetes itself it’s because things are ignored.

The one hallmark of diabetes and the way it affects the feet is something called peripheral neuropathy.

Peripheral Neuropathy is a decrease in sensation in the legs and in the feet to the point where when is really advanced some people can’t even feel anything even if they step on us splinter or step on attack they will have no knowledge of that.

Those are the people we have to be the most concerned with.

They’re the ones if they step on something and don’t realize it. It ‘ll become infected and that becomes a larger problem.


The main way people can combat that is with something simple like a daily foot check.

Checking your feet every night before you go to bed between your toes on the bottom of your feet looking for any redness any bleeding any pus essentially anything that wasn’t there the day before and if you find something and you’re checking every day you know it’s not more than 24 hours old.

If you find something you pick up the phone you call your podiatrist and the sooner you get to them too soon you’re able to get it taken care of.

The key to diabetes and the key to keeping your feet in good health with diabetes is prevention.

If you don’t have a podiatrist make sure you establish a good relationship with one if you have risk factors you’ll be seeing that podiatrist often and if you don’t then not quite as often but when you know someone’s there for you it makes you a lot more comfortable knowing that you’re going to be able to be walking on your feet for many years to come.
