| * Footwear; all major reviews recommend special footwear for patients with a prior ulcer or with foot deformities. One review added neuropathy as an indication for special footwear. The comparison of custom shoes versus well-chosen and well-fitted athletic shoes is not clear.

| ''Clinical Evidence'' reviewed the topic and concluded "Individuals with significant foot deformities should be considered for referral and assessment for customized shoes that can accommodate the altered foot anatomy. In the absence of significant deformities, high quality well fitting non-prescription footwear seems to be a reasonable option" <ref name="pmid16620415">{{cite journal |author=Hunt D |title=Foot ulcers and amputations in diabetes |journal=Clin Evid |volume= |issue= |pages=455-62 |year= |pmid=16620415 |url = http://clinicalevidence.com/ceweb/conditions/dia/0602/0602_I5.jsp | based on September 2005 search}}</ref>.
