Summary
In this research study, the investigators are evaluating if novel custom foot orthotics improves foot health and mobility for people who are at increased risk of developing foot ulcers. The investigators are comparing different methods of custom foot orthotic fabrication in people who are at increased risk of developing foot ulcers and individuals who are not. Participating in this study involves coming to the VA Hospital in Seattle for up to 12 study visits, lasting up to four hours. If eligible and choose to participate, participants will:
* Wear custom foot orthotics during in laboratory testing for up to four hours
* Receive a foot health assessment
* Walk through the laboratory space so the investigators can see how the orthotics affect the participant's body movement
* Participants will be paid for participating in the study
