Samenvatting

The invention provides an insole (1) comprising a plurality of supporting elements (5A, 5B, 5C) distributed over the insole surface for resiliently supporting a foot. Each supporting element comprises a main supporting portion (9) having a narrowing outer shape, and a widening circumferential buckling wall (7) designed to have a buckling behaviour such that: (i) the buckling wall collapses in reaction to a condition in which an external compressive force exceeds a first force threshold (F1); and (ii) if thus being collapsed, the buckling wall resiliently expands in reaction to a condition in which said external compressive force falls below a second force threshold (F2), which is lower than the first force threshold. In use the insole provides a highly effective dynamically self-adjusting pressure distribution reducing peak pressures under a foot, dynamically when the patient walks. In addition, the insole is compact, non complex, easy to produce, durable and reliable.
