SUMMARYAims This study analysed the effects of specially manufactured insoles on foot pressures in diabetic patients during a 1‐year prospective observation period. Methods We studied 81 type 2 diabetic patients without foot lesions. Using pedobarography three different regions of interest were examined: maximum peak pressure (MPP) of the total foot area, heel region and head of metatarsal bone I‐III. Eighteen patients with high risk pressure (MPP of total foot 474 ± 183 kPa; heel region 278 ± 147 kPa, metatarsal 389 ± 222 kPa) received optimal insole support. Sixty‐three patients as a control group (MMP of total foot 367.7 ± 157 kPa; heel 263.1 ± 127 kPa, metatarsal 339.9 ± 171 kPa) received conventional footwear. Results After insole support a 30% pressure reduction of total foot MMP (474 ± 183 kPa vs. 290 ± 106 kPa) was achieved in the treatment group. After 6 months (324 ± 127 kPa) and 1 year (380 ± 190 kPa) a pressure reduction was found. Between the 6‐ and 12‐month controls plantar pressures again increased. In the control group a significant increase of all peak pressures occurred. Conclusions Early insole support is successful in reducing plantar pressure. A repeated adjustment should be performed every 6 months to prevent foot pressure increases. The comparison of foot pressure development between the two groups showed constant levels in the treatment group. In the control group a marked increase of the pressure values was found. Identification and subsequent support of patients with high ulceration risk may help to reduce the high amputation rate.
