Ski boots were originally leather winter boots fixed to the ski with simple leather straps. As skiing became more specialized, the design of ski boots developed, leading to a split in styles between those worn for alpine skiing and those for cross country skiing, including the introduction of a stiffer leg with the advent of the ski lift.
Many ski boot brands were established including in 1950 the Austrian company Humanic . They started manufacturing leather boots before introducing buckles in 1965 and plastic components in the early 1970s. They changed their name to Dynafit in the 70s.
These boots were purchased in 1975 by the donor’s father when he first learned to ski. The donor took them on when his father moved onto a more modern pair in the late 70s. They were worn until the mid-80s.
