Design Any Sole, For Any Brief.

With complete technical confidence.

Most footwear programs stop at the upper. Our programs cover everything they skipped. With the technical depth, feedback, and practice to make it stick.

You can design beautiful shoes. You understand trends, and you know what the market wants.

Maybe you also have a footwear design degree, or years of industry experience.

And yet, the moment the brief needs a sole designed from scratch... you go quiet.

You try to guess your way through it. You tweak an existing sole, endlessly comparing your work to references.

You send it to the factory, and hope they don't send it back full of corrections...

But often, they do. And you're left wondering why.

Sole design is the one part of footwear that no one teaches.

Designers are told they'll just "pick it up on the job".

So they try to figure it out alone... through YouTube videos, LinkedIn posts, old university textbooks, factory feedback, and trial & error.

This is the gap Sole Design Academy fills.

  This IS for you if:  

  • You rely on colleagues for technical decisions and want full independence

  • You want to offer a more complete service as a freelancer, and charge accordingly

  • You want to qualify for technical, outdoor roles

  • You’re tired of relying on references

  • You'd like to stay competitive with a new specialized skill

  • You want to confidently explain your design decisions

  This ISN'T for you if:   

  • You’re looking for a general footwear course

  • You're looking for a 3D course.

  •  You're looking for a CAD course.

  • You're looking for a mould-construction engineering course.
  • You want to learn sole chemical compound formulas
  • You’re not ready to invest in becoming a specialized designer

  • You’re looking for shortcuts instead of technical depth

Meet Your Instructor:

Defne Yalkut

Defne is a technical footwear designer and sole expert based in Milan, designing for global brands.

She started her career in 2004 at Vibram, the world leader sole brand. In 2015, she created the niche Sole Design program at IED. 

Her found her purpose in teaching ; sharing hard-earned knowledge with footwear professionals and aspiring designers.

She believes sole design mastery is what separates good from great: the point where creativity meets technical authority, and a design truly comes to life.

Nothing makes her happier than watching her students level up.

No matter your background, our programs will take you from uncertainty to technical clarity.

Here’s what you’ll design (confidently and independently) after just a few weeks at the Academy:

Student Highlight - Adam Frk

"Although I've designed soles before joining the Academy, I felt that I had huge gaps in knowledge that even the suppliers and technicians in China couldn't fill in.

That's why I joined Sole Design Academy, and I have to say that I don't regret one single euro! :)

I am also using the manuals and guidebooks regularly. The live sessions are also great!

Since joining, I have already designed & produced another sole for a footwear collection. The development process was much smoother, and the result is more competent.

All thanks to this Masterclass!"

 Does designing soles feel slow, almost impossible?

This is a skill that experience alone won't build.

Sole Design Academy gives you the complete sole design system. Including all the tricks and hidden rules most designers are never taught, but every factory expects you to know.

Step 1: 

MATERIAL & WORKFLOW MASTERY

Choose materials and moulding techniques based on performance needs and budget constraints. 

Move from brief to prototype faster, with a real structure. Design within manufacturing constraints from day one.

Step 2:

PERFORMANCE DESIGN MASTERY

Hiking. Trail running. Trekking. Winter. Basketball. Tennis. Safety.

You’ll understand the performance logic behind each segment, and know exactly how to apply them independently. No more guessing and "hoping this works".

Step 3:

SNEAKER SOLE DESIGN MASTERY

Now that you mastered designing technical soles for various segments, you'll master advanced design and decoration techniques for sneakers and urban footwear.

Think: spraying, painting, TPU film, digital printing, surface finishings and more. This will unlock a whole new world of authenticity.

Step 4:

PERFORMANCE-FIRST SKETCH MASTERY

Thanks to our step-by-step sketching workflow breakdowns, you’ll have a clear, repeatable sketching framework. 

All you need is a pencil and paper. We teach design, not 3D.

"After taking the Masterclass I applied the technical knowledge into a New Balance / Pensole apprenticeship application & I ended up getting accepted - my career took off from there."

Nico - Footwear Designer @ Alexander Wang

"This is one of the best investments I've made in my professional development. The course helped me identify mistakes in my design process that I hadn't noticed before.

If you want to go deeper into footwear development and truly understand the relationship between function, aesthetics, and biomechanics, this is exactly what you need."

Christina Kutsiy

 After getting hired at La Sportiva, Laurits said:

"Thank you for making this community for like-minded people who want to have a good chance at getting a job in the industry. It helped me to better understand what drives performance in footwear and how to apply it."

Laurits Faaborg 

"During my recent meetings I felt more confident providing feedback on construction, materials, and design. I also find myself being more critical of my design lines to ensure the designs are feasible.

I really appreciate learning from Defne's experience and am grateful to share this valuable journey alongside so many talented designers."


Amalia Castro

"The course was invaluable to me, not just in learning key fundamentals of sole design in a variety of categories, but also in getting detailed insight into the benefits and limitations of various manufacturing techniques."

Charles - Senior Footwear Designer @ Footsoldiers

"When I moved to the U.S. from Ukraine, the course helped me to land a job quickly.

After completing your course I developed over 15 soles in two seasons, and my colleagues began coming to me for advice."

Tatiana Kalashnik - Lead Footwear Designer

 

"After all the precious information you gave, going to the shoe store felt completely different.

I found myself happily lost among the outsoles, finally understanding the performance rules behind each choice. "

Basak Scarpino

"I am changing my footwear sector from sport/ casual, to more high-performance, I believe your course will help me have a much better start!"

Elizaveta - Footwear Developer @ Birkenstock

"Defne's course was my first real introduction to the footwear world, with her I learned the whole process of sole design, from brief to final product. There is not a day I won't use the knowledge she taught me."

Ibai Fletas - 3D Designer @ Camper
