    Increased pressure of the plantar surface of the foot is highly associated with the onset of ulceration. Several factors have been associated with the presence of abnormally high plantar foot pressure including: (i) increased body weight (ii) foot structure (iii) Walking strategy [1]. It is predicted that the biomechanics of the foot are influenced by the structure of the foot, primarily the Medial Longitudinal Arch (MLA). The objective of this study is to decipher if Body Mass Index (BMI) and the MLA have a direct effect on dynamic peak plantar pressure for healthy subjects. Functionality of the foot and ankle was also investigated through performing dynamic plantar pressure profiling at specific events during stance phase of gait (Heel Strike, Mid stance and Toe off). Following a clinical lower limb examination, the Tekscan HR mat was utilised for this study. Five trials were preformed per foot per subject. Results indicated to the preferable normal MLA as this produced a low plantar pressure distribution in all cases. The highest pressure was seen at heel strike for the flat arch (360 N/Kg). The 2nd and 3rd metatarsal head region recorded the highest normalised force for all arch types during dynamic analysis. BMI had a non significant effect on function and plantar force. Future work involves comparing this healthy database to a demographically matched diabetic group.
