Haflinger, producing boiled wool slippers and clogs in Germany for the last fifty years introduced its quality constructed footwear to the United States in 1990. Firm cork and rubber outsole materials support their notion that feet require a consistent surface for maintaining good health. The boiled wool upper materials do well to keep the feet cool in the summer and warm in the winter. The removable liner allows the use of orthotics for high risk feet. Haflinger slippers can be used as in-house slipper or as an outside shoe, all without sacrificing style.
