Shoe inserts are often used to correct for foot misalignment or overloading during walking and running. To understand the interaction of medial wedge insoles and different surface hardness and geometry, we investigated plantar pressure and rearfoot movement. Twentyeight subjects with normal feet were tested when walking with and without insole on all combinations of hard and soft surface and level and upstairs walking. The main changes in load distribution and rearfoot movement were found between wearing insoles and not wearing them while differences between surfaces were small. In conclusion, surface hardness did not change the general effects of the insoles.
