A Doctor may order a foot orthotic for a misshapen, or injured foot, to relieve pressure or to align the foot . Many Orthoses treatments can allow the patient to wear shoes designed specifically to treat the abnormality and in other cases special boots or braces must be worn.
As Wikipedia notes: Diabetic shoes are sometimes referred to as extra depth, therapeutic shoes or Sugar Shoes. They are specially designed shoes, or shoe inserts, intended to reduce the risk of skin breakdown in diabetics with pre-existing foot disease.
Wikipedia also notes that poorly controlled blood sugar can damage many parts of the body, including the nerves and vessels that go to the feet. Because of this, people with diabetes have an increased risk of developing foot problems. Wearing specially designed shoes can help reduce the risk and promote healthy circulation in your feet.*
Shoes for Arthritis
Arthritis can be very painful and make it difficult to fit into a shoe without having a custom fit. Quality shoes with custom inserts and/or pads can make walking more comfortable.
