Diabetic ulcers: Diabetes causes a condition known as microangiopathy. This is the clogging of microscopic blood vessels that feed skin and sub-cutaneous tissues. Therefore, if there is any pressure point on the foot, the blood flow is essentially cut off and the skin breaks down as the skin cells die from lack of blood flow.

Neuropathy: Diabetics often times develope decrease in sensation of the feet. This in conjuncion with having possible foot demormities such as bunions, hammertoes, or pominent metatarsal bones may lead to diabetic foot ulcers.

Diabetic leg ulcers: Diabetics get ulcer due to multiple causes including healing problems, nerve issues, circulation problems with the large and small arteries and pressure issues.
