Wellbeing starts from the ground up

It's not just how you step. It's how your body learns to compensate.

We take between 5,000 and 20,000 steps a day. Your body feels every one of them.

Your feet are the first point of contact between your body and the ground. Every step impacts your knees, hips, back and posture. It's up to you to choose the right support.

    Marc F.

    Amateur runner

    Laura S.

  • I bought them for everyday use and the difference is noticeable from the very first moment. They're comfortable, light and fit really well in my usual shoes.

    Clara M.

Discover what makes our products innovative

SYLACORE was born from more than 38 years of clinical experience applied to foot biomechanics.

Over that time, we realised something: many people do not take care of their feet, or wait too long to start. A custom-made orthopaedic insole takes time, appointments and a clinical process that many people keep postponing.

That is why we created SYLACORE: a simple first step to start taking care of yourself today. SYLACORE does not offer orthopaedic insoles or custom-made medical devices; it offers a personalised, accessible solution to move from doing nothing to caring for your feet. We use your answers and, if you choose Advanced, a 3D scan of your feet to design your insole, which we manufacture in 3D with a 100% in-house system backed by more than 38 years of clinical experience.

We are not a medical service. SYLACORE does not diagnose or treat conditions, and does not replace the assessment of a healthcare professional. We offer a solution focused on everyday wellbeing and comfort.

Our roots

SYLACORE has been developed within Esade's entrepreneurial ecosystem in Barcelona, through the eWorks incubator, and validated at 4YFN, the startup event of Mobile World Congress (2026 edition). From there, we combine health, design and innovation to create a new generation of custom insoles designed to be with you every day.

FAQs

Frequently asked questions

What sets us apart?

SYLACORE insoles are custom-designed using 3D printing technology and in collaboration with expert podiatrists. They're not generic: they're personalised according to your data, needs and intended use, offering greater comfort, support and durability. If you choose Advanced, we also incorporate a 3D scan to adapt the design to the shape of your feet.

Do I need to have a foot problem to use them?

You don't need to be in pain to take care of how your body moves.

SYLACORE insoles are designed to improve daily comfort and provide better support with every step, whether at work, in sport or in your daily routine.

If you already experience symptoms, pain or an injury, it's best to consult a healthcare specialist for a full assessment.

What happens from purchase to receiving my insoles?

First, you choose your insole model and customisation level. After purchase, you complete the quiz with details about your activity, footwear, weight, height and how you plan to use them.

If you choose Advanced, you receive a link to download our mobile app and complete the 3D scan of your feet step by step. With all that information, we design your insoles, manufacture them on demand with 3D printing and ship them to your home.

How long will it take to receive my insoles?

Once you place your order and complete the quiz, we manufacture your insoles on demand.

You'll receive your insoles within 7–14 working days.

Can I use SYLACORE insoles in any type of shoe?

Designed to fit naturally into your daily life.

SYLACORE insoles are designed around your activity, your footwear and how you plan to use them. That's why they adapt to most sports, casual and work footwear.

Which customisation level do I need: Essential or Advanced?

Essential is the right option if you want a personalised insole based on the quiz, without the 3D scan. It's a good choice if you don't have an iPhone or iPad compatible with Face ID.

Advanced is the most complete option: it combines the quiz with a 3D scan of your feet to capture their exact shape down to the millimetre. The more data we have, the better we can adapt the design to your foot, activity and footwear.

What do I need to complete the 3D scan?

To complete the 3D scan, you need an iPhone or iPad compatible with Face ID. After purchase, you'll receive a link to download our mobile app and follow the steps to scan your feet.

If you don't have a compatible device, you can choose Essential, borrow one from someone close to you or contact us so we can guide you.

Are these medical or orthotic insoles?

SYLACORE is not a medical service and our insoles do not replace the assessment of a healthcare professional.

We design personalised insoles focused on improving comfort, support and wellbeing in your everyday life. If you have symptoms, pain or an injury, it's best to consult a healthcare specialist.

What is the difference between a SYLACORE insole and a standard insole?

A standard insole does not take into account who you are, how you move or how you plan to use it. At SYLACORE, we start from data about your activity, footwear, body and habits.

If you choose Advanced, we also add a 3D scan of your feet to capture their exact shape down to the millimetre. With that information, we design and manufacture your insoles on demand with 3D printing.

Can I move the insoles between different shoes?

Yes, you can use them in different shoes as long as the footwear is compatible with the type of insole and has enough space for it to fit correctly.

Even so, each model is designed for a specific purpose: sport, casual or work. For the best experience, we recommend using each insole in the type of footwear it was designed for.

Can I return them if they don't work for me?

Yes. Even though they are clearly personalised products and we cannot reuse them for someone else, SYLACORE has a distinctive commitment to our customers: you can request a return.

You have 14 calendar days from receiving your order. We refund the cost of the insoles; return shipping costs are paid by the customer. If the insoles don't work for you, contact us and we'll explain the steps for arranging the return according to the applicable conditions.

How do I know which type of insole is right for me?

At SYLACORE you'll find three lines designed for different lifestyles: Work, Casual and Sport.

Each collection includes models designed for specific purposes, reflected in their own names. During the process, we guide you step by step to choose the insole that best fits your activity, your footwear and how your feet feel at the end of the day.
