Insoles of uniform softer material reduced plantar pressure compared to dual-material insoles during regular and loaded gait

There is limited evidence on the efficacy of insole materials to reduce plantar pressure during regular walking and loaded walking. In-shoe pressures subjective footwear comfort were recorded in twenty healthy participants at a self-selected treadmill speed six conditions: two commercial insoles or no insole, with without carrying load backpack. A single-material comprised polyurethane, had reduced density compressive stiffness compared dual-material added viscoelastic material rearfoot forefoot regions. Load carriage increased peak across foot. Both rearfoot. Yet, softer also attenuated did not appear cause bottoming-out polyurethane. Plantar changes affect perceived comfort. The was more effective reducing pressure, further research would confirm if this influences injury prevalence.
