The Heliane model from Berkemann is characterized by comfort and function. The partial stretch insert on the inside of the shoes relieves pressure and chafing points and thus alleviates discomfort or even pain, such as that caused by a hallux valgus, from the first minute of wearing them. The visual highlight here is that the highly flexible stretch material used cannot be distinguished from real leather at first glance. In addition, the shaft and sole of this model are connected with an elaborate hand seam, which gives this open clog additional flexibility.
