In the past decades, the scientific focus regarding calcaneus fractures was the choice of operative or non-operative treatment modality. Although the evidence is ambiguous, recent meta-analyses suggest that operative therapy is associated with a higher likelihood to resume pre-injury work, to reach a higher level of physical function and fewer problems when wearing shoes. However, non-operative therapy has significant less complications and infections. Typically, aftercare includes non- or partial weight bearing, but protocols are different and often not very specific. In fact, there are no studies published comparing different procedures or special supporting devices. Recently, a heel-unloading orthosis ('Settner shoe') was introduced in aftercare for calcaneus fractures, allowing walking by shifting the load to the middle- and forefoot. This orthosis does not only enable early mobilization of patients suffering one-sided fractures, but also permits going following two-sided fractures, avoiding the otherwise necessary wheel-chair mobilization. The 'Settner shoe' can be applied in non-operative therapy and following operations. Specifically in calcaneus fractures, early regain of physical activity has been highlighted as one of the key factors for quality of life and the ability to return to work. Thus, the investigators hypothesize that mobilization with the 'Settner shoe' results in higher physical activity within the first 3 months and secondly improves ability to return to work in calcaneus fracture patients aged 18-60 years. Further outcome criteria are the American Orthopaedic Foot and Ankle Society's (AOFAS) ankle-hindfoot assessment, a 3-dimensional gait analysis, and the EQ-5D-3L questionnaire. It is the first trail applying a standardized aftercare in patients suffering from calcaneus fractures aiming to improve the non-operative part of treatment. Furthermore, the trial clarifies, whether the economical effort for the equipment acquisition is scientifically justified.~The investigators hypothesize that mobilization with the 'Settner shoe' results in higher physical activity within the first 3 months after calcaneus fractures.~Research questions~Does the application of a heel-unloading orthosis ('Settner shoe') independent of operative or non-operative therapy of a calcaneus fracture improve:~the physical activity (active minutes per day)?~the quality of life (EQ-5D-3L)?~the foot function (AOFAS)?~the time necessary for return to work in patients between 18 and 60 years?
