This study will assess the ability of different orthotic insole treatments to reduce pressure
under the ball of the foot. This is important for people who have diabetes because their feet
are at higher risk of foot problems in this area. This study will involve the participants
wearing a a range of insoles produced by milling, handmade processes and additive manufacture
along with normal orthotic footwear. A researcher will measure the pressures under the feet
while the participants walk wearing the orthotic insoles.
