Pashion Footwear is a startup creating the world’s first fully convertible high heels.

As Product Director, I oversee the design of our innovative products.




Inventing Convertible Heels


The fundamental innovation behind our convertible high heels is our patented removable Stelo technology, an invention which I developed. Nearly all aspects of our shoes, from the upper to the sole materials, are specially engineered to optimize the shoe’s transformation between heel and flat. The Stelo provides rigidity to the shoe when worn as a heel as a traditional shank would. The heel is specially designed to stay securely installed during use, and remove easily when the shoe is to be transformed to a flat. Altogether, our shoes utilize several cutting-edge materials and processes to make a product considered impossible by the footwear industry possible. 




Designing Seasonal Product Lines

Illustrator, Fusion 360


Pashion releases four seasonal launches a year.

Each season begins with the creation of a line plan.
Given revenue targets and a budget for the season, I utilize footwear-specific trend and color forecasts, sales analytics, and customer feedback to plan a line that appeals to both new and existing customers.

Once the line plan is confirmed, I create tech packs for the roughly 25 new upper styles, graphics, embroideries, 3D CAD, etc. for the season and provide them to the supplier.

3D CAD & Revision examples

I iteratively review and revise product samples until the full product line is confirmed. Products then move to production and I address any quality concerns that arise.




Rendering 3D Assets

Blender, Photoshop, Coding


Given the transformative nature of our shoes, renders are the most effective method to show their ability to smoothly convert between heel silhouettes and heights. I am responsible for all rendered product imagery, as well as miscellaneous marketing assets. This includes modeling new uppers and heels, rigging them to transform between flat, 1.5”, 3”, and 4” modes, and creating new upper materials.
