The purpose of this study is to collect thermal images of diabetic patients' feet to evaluate the performance of Feetsee - foot monitoring device for periodic evaluation of the temperature over the soles of the feet for signs of inflammation.

The aim of this study is to collect a database of thermal images of the diabetic persons' feet, and non-diabetic control groups' feet images, which in turn will enable us to build a system based on a mobile thermal camera and a mobile application for possible indication of signs of inflammation in feet. Enrolled participants will undergo a detailed history and physical examination of the foot at the beginning of the procedure day. Then the thermal images of the patient's feet will be taken. Participants will be also asked to take thermal images of their feet according to very well-explained instructions provided by the sponsor. Thermal images using the reference thermal camera will be taken following the Feetsee thermal camera. The images will be unidentified, collected, and stored for the development and performance evaluation of the Feetsee device Algorithm. At the end of the study procedure, participants or their caregivers will receive a short questioner on their experience with using the study device.
