The Heliane model by Berkemann is characterized by comfort and function. The partial stretch insert on the inside of the shoes relieves pressure and chafing and thus reduces discomfort or even pain caused by a hallux valgus from the first minute of wear. Optical highlight here is that the highly flexible stretch material used cannot be distinguished from genuine leather at first glance. In addition, this model combines the shaft and sole with an elaborate hand seam, giving this open clog extra flexibility.
