A hybrid approach to the compliance testing of training shoes

There is, as yet, no totally rational method for testing training shoes. The situation is complicated by the coupling that exists between the physical characteristics of the shoes and the biomechanical response to them. This paper sets out to establish a basis for the physical aspects of testing, and shows how the biomechanical response may be integrated into a suitable model. The basic assessment of the compliance properties of training shoes was carried out by the measurement of load‐deflection curves. The analysis of these curves was based on the McMahon/Green two mass, two spring model of limb‐ground interaction, which defines the tangent modulus of the load‐deflection curve as the relevant quality parameter. For a selection of 30 shoe types, the load‐deflection curves were analysed to show how a systematic approach may be developed to understanding the variances in the shoe characteristics.
