The primary goal of therapeutic footwear is to prevent complications, which can include strain, ulcers, calluses, or even amputations for patients with diabetes and poor circulation.
[2] Neuropathy can also change the shape of a person's feet, which limits the range of shoes that can be worn comfortably.
[3] In addition to meeting strict guidelines, diabetic shoes must be prescribed by a physician and fit by a certified individual, such as an orthotist, podiatrist, therapeutic shoe fitter, or pedorthist.
[5][6][7] The evidence for special footwear to treat diabetic foot ulcers is poor[8] but their effectiveness for prevention is well-established.
Technology for measuring the pressure within the shoes is recommended during designing diabetic footwear.
