ZipFit was born from the life's work of Sven Coomer, a true pioneer of ski boot fitting. He became obsessed with the relationship between boot and skier, learning from elite coaches and eventually designing some of the most influential boots in history — including the 1972 Nordica Astral, the first two-piece plastic shell with a separate liner, and the 1975 Nordica Grand Prix, the template for essentially every modern ski boot. In the 1980s, he opened Footloose in Mammoth, where he continued innovating: designing Superfeet orthoses, creating the first foam-injected liner, and ultimately developing OMFit cork, a natural alternative that would become the cornerstone of ZipFit's liners.

Today, ZipFit liners are still handmade by master artisans in Montebelluna, Italy — a living testament to Sven's belief that there are no shortcuts to a perfect fit.
