Thickness-Varied Soft Surface on Shoe-Insoles Based on In-Shoe Pressure Measurement

Comparing a Thickness-Varied Soft Surface of Custom Made Shoe Insoles Based on Plantar Pressure Analysis in Shoes, to Insoles With Even Thickness Surfaces: A Cross Sectional Study Design

The goal of this cross-sectional study is to evaluate a new shoe insole manufacturing method with the goal of further preventing foot ulceration for people with diabetes. This is achieved by decreasing pressure under risk areas of the foot, often on the insole; the interface between the shoe and the foot. The main question it aims to answer is:

Does a thickness-varied surface based on plantar pressure measurement decrease pressure at high risk areas compared to even thickness surfaces.

Researchers will compare three different pairs of insoles for each participant.

Participants will partake in two sessions. The first one being a pre-measurement and foot status for manufacturing the insoles. During the second session, three pairs of insoles will in a random order be tested for each participant. The pressure measurement of the insoles will be made using F-Scan(TM), while participants walk.
