Path 1:

Guidance on a Sole Project

From concept to manufacturable sole. No wasted time, no wasted budget.

You bring the brief. Defne works through every step and every decision with you, under NDA.

You will understand not just what to do, but exactly why. Every material choice, every line, every factory requirement explained as you design it.

By the end, you will have a technically sound, fully manufacturable sole design, and the process to replicate it on every project that follows.

Path 2:

Strategic Portfolio Upgrade

Position yourself for the brands, rates, or clients you actually want.

Together, you and Defne will identify exactly what your portfolio is missing, what it needs to communicate, and what to add to demonstrate strong technical thinking and production-ready sole design skills.

Every addition is strategic. The result is a portfolio backed by work you can defend, explain, and replicate, not just show.

"I feel empowered by all the knowledge I've acquired so far."

My technical vocabulary has grown, and the desire to pick apart our entire outsole line is growing. I also love how reachable Defne is.

 I can actually back up my designs with technical knowledge. Not just saying "pretty" or "looks good".

I'm confident I can deliver as many functions as possible within my client's budget. The program also gave me the confidence to feel knowledgeable enough to go try making a tech-pack making app :)

I love connecting with other students, sharing stories of achievements and navigating problems together.

Tae Querney. Senior Footwear Designer with 15+ years of experience.

"The Sole Design Masterclass is the most extensive and detailed resource for sole design that I have ever seen in the industry."

To have all that knowledge documented in one place is invaluable. The mentorship is great for people that are at a stage where they need to apply the knowledge to their specific live industry projects.

Defne gives quick feedback and 1:1 sessions to help improve your ability if you are looking to accelerate your skillset on a tight timeframe. "

Lead Footwear Designers at a Fashion Footwear Brand

"Defne is not just a great designer, but also an incredible mentor to work with."

She has a strong sense of design and is extremely professional, but what I appreciate most is how involved and supportive she is throughout the process.

She takes the time to guide, explain, and genuinely help you grow. Beyond design, her inputs and advice have been very valuable to me personally as well. Working with her has been a great experience, and I’d highly recommend her."

Are you ready to design your next sole differently?

 Even if it isn’t your first project… This time you won't be guessing.

You'll have Defne's hands-on support at every step. 

And thanks to the Masterclass, you'll also know what factories expect, understand material trade-offs, design with intention and feel technically fluent.

As a Coaching Student, You'll Also Get Access To the Masterclass:

+ Two Bonus Modules on Fashion Soles & Sustainable Sole Design.

No project will catch you by surprise. Not even high-heels, branded sneaker soles, sandals, or moccasins.

“Okay… but what if I can't remember all this?” - You will.

Because we didn’t just give you lessons to watch. We built you a Technical Library to act as your "sole assistant."

Grip & Traction Handbook

Inside, you’ll find:

  • Real-world lug geometries for wet, dry, snowy, icy, rocky and oily surfaces

  • Visual breakdowns of traction logic

  • Surface-specific design references you can open while sketching

Imagine designing a trail sole and knowing that your lug spacing and angle make sense.

No more copying references or second-guessing your decisions. 

Performance Rules Manual

Imagine always having performance rules for major sports at your fingertips.

Road & Trail Running. Hiking. Basketball. Tennis. Water Sports. Work & Safety & more.

Instead of: “Is this lug shape okay?” or “Should I use the biomechanical S shape in this case?”

You’ll know.

When you understand performance rules, your confidence changes and the sky becomes the limit to your creativity.

Material Properties & Costing Guidebook 

If you lose confidence the moment material properties and cost implications enter the conversation, this one's for you.

This guide contains technical insights collected through decades of working directly with factories, technicians, and mould-makers.

Inside you’ll understand:

  • Which compounds make sense for which budget and performance / aesthetic requirement

  • Where you can reduce cost without killing performance

Imagine sitting in a meeting and confidently explaining why you chose a specific material & moulding technique, and how it will impact cost.

Common Errors Prevention Guide

Nothing hurts more than sending a design to a factory and realizing you messed up something easily preventable.

Sharp undercuts. Impossible mold situations. Thickness inconsistencies.

After 11 years of teaching, Defne has seen the same mistakes over and over again.

This guide helps you avoid them before they cost you credibility, because preventable mistakes shouldn’t define you.

Thanks to our Missions, You'll Apply (and remember) What You Learned:

Here's What Our Students Say:

"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! :)

Since enrolling, the sole development process is much smoother and the result is much more competent. All thanks to this masterclass!

Adam Frk

"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

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 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

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 better understand what drives performance in footwear and how to apply it.

Laurits Faaborg - Footwear Designer @ La Sportiva

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 - Footwear Designer

"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 Astrella - 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 - Footwear Designer

It's worth every penny!

It gave a balanced approach of creative thinking and technical understanding to footwear tooling. From materials, color, form, function production methods, and sustainable practices, the course really exposes you to everything you need to know about designing nearly any type of sole.

Woby Lang - Barefoot Shoe Specialist

"My favorite parts were the assignments to create our own outsoles. To share and see what classmates have created and get professional feedback from Defne was incredibly valuable. She is a true professional."

Coby Laureijs - Freelance Footwear Designer

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