3D Foot Scanner Reliability for Footwear Fit and Design

The investigators will carry out a proof-of-concept study in 20 adult healthy male and female volunteers in order to: assess a 3D foot scanner's reliability. Specifically, the investigators will assess its variability during repeated foot scans of the same subject's foot. Three repeated foot scans will be carried out by two different examiners to measure intrarater and interrater reliability (Intraclass Correlation Coefficient

Inclusion Criteria:Healthy men and women aged 18 years or overAble to walk unaidedAble to walk up steps (the 3D scanner requires a small step on to the device to enter the correct position for measurement)Willingness and capacity to participate in the study and to sign the informed consent formExclusion Criteria:Diabetes mellitus diagnosisInability to ambulate independently without walking aidsNo obvious foot deformitiesNo history of foot surgeryNo pain, injuries or medical conditions affecting the legs or lower backAny issues around balance (participants must remain standing in position for the approximately fifteen seconds required to obtain the 3D scan of their feet)Health conditions that impact foot morphology
