Diabetic Foot Ulcer

Understanding nerve-related foot conditions and how specialized footwear helps

Common Diabetic Foot Conditions

Neuropathic Ulcer – An open sore on a numb foot, usually under the ball of the foot or heel, caused by unnoticed pressure or injury.
Ischemic Ulcer – A wound caused by poor blood flow, often on the toes, edges of the foot, or heel.
Neuro-Ischemic Ulcer – A slow-healing ulcer caused by both nerve damage and reduced circulation.
Callus Formation – Thick, hardened skin over pressure points that can break down into an ulcer.
Charcot Foot – Weakening of the bones and joints that can change the shape of the foot.
Foot Deformities – Hammer toes and bunions that create pressure points inside shoes.
Infection & Cellulitis – Bacterial infection of an open wound, which can spread quickly.
Dry, Cracked Skin – Skin fissures that allow bacteria to enter the foot.

Neuropathic Ulcer

A painless wound that develops when nerve damage hides the warning signs of pressure or injury.

Ischemic Ulcer

A painful, slow-healing wound caused by reduced blood supply to the foot.

Callus

Thickened skin over high-pressure areas that can hide a developing ulcer underneath.

Charcot Foot

A condition in which weakened bones and joints collapse, creating new pressure points.

Key Symptoms — When to Seek Help?

An open sore, blister, or cut that is not healing within a few days.

Black, blue, or pale skin discoloration, especially on the toes.
