New Proposed Method for the Analysis of Biomaterials in Foot Insoles

In this paper, a stage of a research activity in the orthopedic field for testing modern materials composing foot insoles at different tasks, such as simulating walking, running, orthostatic position, or sitting, is described. This stage concerns the testing of five samples of materials taken from five patterns of inlets, subject to a degradation process, over different time periods. The degradation process consists of subjecting the immersed samples to a 15–20% saline solution at static loads of about 400 N. The salinity percentage is established so that the solution obtained is similar to that of sweat, which occurs especially in the warm season while wearing the shoes. The exposure to degradation times is established at 3 and 7 days, respectively. The main aspects are the degree of compaction and the degree of deformation of the samples, as a result of maintaining different times in degradation conditions.
