A spring or alternative elastic, resilient, compressible media cassette for a touring-style ski binding, such as used in alpine touring or telemark skiing. The touring ski binding slip differential cassette provides the skier with variety of tuning options to manually adjust binding size, stiffness, and range of motion. Manual adjustment of binding size, stiffness, and range of motion enhances the touring ski binding ease of use, adjustability, and overall capabilities, further progressing the touring ski binding. In addition, the slip differential cassette provides the touring skier with cassette presets that match each skier to a predetermined binding size, stiffness, and range of motion based on skier weight and ability.

A linkage binding for coupling a user's shoed or booted foot to another object, such as a ski or snowshoe. The linkage binding may include an upper plate including an upper surface to which a user's shoed or booted foot is to be secured, a lower plate including a lower surface to which another object is to be secured, a front connecting link hingedly attached to both the upper plate and the lower plate, and a rear connecting link hingedly attached to both the upper plate and the lower plate to form a 4-bar linkage.

An improved highback adjustment system for a splitboard boot binding. A captive strut is mounted on the spine of the highback, the strut having a forward lean adjustor block such that rotation or sliding of the block lengthens or shortens the strut. The combination provides a broadly adjustable range of forward lean bias in small increments and the block is readily disengaged and stowed on the highback when not needed. Advantageously, the mechanism that can be operated and adjusted without tools, even with gloved hands, a significant benefit in winter conditions, and does not jam with snow. Methods of use of the improved forward lean adjustor and highback are also disclosed.
