Hassel is also one of those classic Berkemann models that simply cannot be improved. This model has been in the range for decades with its durable look and unrestricted functionality. Particularly noteworthy are the number of four narrow straps, which can be adjusted with buckles and thus optimally adapt to "difficult" feet or foot shapes and thus ensure a perfect fit. The softly padded insoles provide additional comfort, while the cup-shaped heel socket relieves the strain on the joints and provides secure support.
