Camper has joined forces with Tencel, a brand of the Austrian chemical group Lenzing, to produce a shoe collection using sustainable Lyocell fibers. The Spanish-based company has redesigned its Right and Upright boot and bootie to include Lyocell fibres derived from sustainably-grown wood sources. For the collection, the fiber has been blended to create a webbed structure, which creates a sock-style boot.

Camper is estimated be the first footwear brand to feature a knitted upper women’s boot using the fiber, according to Lenzing. Camper plans to eliminate the use of virgin plastic in its uppers by 2022.

Tencel launched Lyocell at the Techtextil fair in Frankfurt in May 2015.
