description
The Computational Design for EQLZ® 247 takes inspiration from three natural systems - the scales of a shark, the laminar flow of water, and a pressure map of the human foot.

The outsole pattern utilizes macro and micro scale tuning. Each of the 220 individual scales are unique in their geometry, and respond to pressure map data not only in size, but with variable section profiles as well as optimized orientation along a gait or flow line.  

Each scale is flared to extend .5mm proud of the surrounding outsole surface, and stands individually on a thin web, providing a balance of performance, flexibility, and on-court feel.  
eqlz® 247 natural pattern design exploration

The individual scale form was inspired by the scales of a Shark. Explorations in biomimicry studied the relationships between fluid motion,  propulsion, and traction. A variety of scale forms were studied to balance the performance and aesthetic of the outsole geometry.

pressure-responsive outsole design

Human performance is a key driver for EQLZ® 247. A computational system was created to allow for a wide range of outsole pattern exploration providing macro and micro level tuning to respond to a pressure map of the human foot. Control over scale orientation, spacing, size, section profile, and many other parameters were utilized to balance performance, flexibility, and on-court feel.

Each of the 220 individual scales were modeled as a dynamic, procedural object that can respond to pressure map data depending on its location on the outsole. Custom size, orientation, and section profiles were continuously varied across the outsole to maximize the dynamic responsiveness of the pattern. Several computational processes were utilized to ensure consistent radiusing of filleted edges and to maintain strict, dimensional compliance with respect to performance, manufacturing tolerances, mold-making parameters, and long-term durability considerations. The scales sit .5mm proud of the surrouning outsole surface, on a super-thin web to establish exceptional performance, feel, and flexibility.

product launch animation teasers

Triptych series of animations highlighting the fluid forms of the shoe. Utilized in social media campaign leading up to product launch. Animations were simulated and rendered in Houdini and Karma.

product visualization

Visual communication is a critical aspect of the design process. Various methods of design visualization have been utilized for an expansive number of uses including marketing, social media, vendor and manufacturer communication, digital prototyping, colorway exploration (not shown), and others.
