The structural response of gyroid lattices are examined with experimental and numerical analyses with particular focus on the influence of geometric parameters on compressive behaviour. The behaviour of fluid flow within the lattice and the influence of different geometric parameters is also characterised to evaluate permeability and pressure redistribution. Building on this, a solid-liquid composite model is developed, integrating experimental observations with numerical simulations to capture the behaviour of fluid-filled gyroid lattices for the development of a homogenised constitutive material model. A gait-driven numerical framework is proposed to simulate realistic insole loading scenarios, verified against experimental plantar pressure measurements. This model is used in an optimisation algorithm designed to generate customised responsive insole properties, enabling the integration of fluid-filled lattices into practical orthotic applications. The findings demonstrate that fluid-filled lattice insoles can significantly reduce peak plantar pressures during gait, thereby improving user comfort.
