The sole technology creates the perfect combination of air and movement. Up to 300 air hemispheres in the insole guarantee optimal circulation and a relieving suspension for unparalleled comfort with every step. Interchangeable footbed: with the interchangeable footbeds, shoe comfort can be easily optimised. The replaceable insole allows you to replace them with orthopaedic insoles, fresh soles or heat insoles as needed. High-quality material: the shoes are made of textile, which is both comfortable and particularly durable.
