Gravel YS

“Gravel YS” sole: Filtration & Stability

Edited by Yoann Stuck

The «Gravel YS» sole, developed in exclusive collaboration with champion Yoann Stuck, is designed for hybrid adventure. It meets the demands of a versatile riding style, ensuring a smooth transition between tarmac and off-road terrain. It filters out vibrations on the road whilst retaining the necessary responsiveness on rough terrain, ensuring unflagging comfort over very long distances.

Usage & Durability :

  • Intended use: A versatile, high-performance design, ideal for mixed-terrain rides combining road and trails (Gravel, Road-to-Trail).
  • Fitting: Easy to adapt and tailor to your trainers (see cutting instructions).
  • To preserve the technical qualities of the materials, prefer natural drying away from sources of heat (direct sunlight, radiators).

Your ideal profile: A versatile cyclist (road and off-road), a fan of long distances, looking for a bike that offers a good balance of comfort.

V-STABILITY

THE FOUNDING ARCHITECTURE

Patented by Emmanuel Contal, this double resin shell is the structural heart of all WARUJU insoles. A true technological identity, it encourages a physiological approach to anticipate imbalances in the musculoskeletal system.

PRESS-TIME

THE SELF-MOULDING EFFECT

Each foot has its own unique relief. This technology uses self-moulding materials capable of gradually adapting to your morphology. Over time, the material accommodates the support zones to create a personalised footbed. The foot takes on its natural shape, gaining in stability and comfort.

MTP-SOFT

PROPULSION SUPPORT

This ergonomic relief supports the metatarsal heads, reducing pressure. The foot regains its strength for efficient, fatigue-free propulsion.

FLEX-ACTIVE

NATURAL DYNAMICS

Thanks to a precise calibration of the flexibility, adapted to each size and practice, WARUJU synchronises the material with your need for movement. This concept ensures that there is no pressure blockage, which optimises dynamics.

35-SHORE

AN EXTENSION OF THE FOOT

The skin of the foot is both resistant and supple. To meet the foot's need for comfort in all situations, we have chosen materials that are as supple as the skin of the foot. The sole offers an ideal compromise between stability and comfort.

The WARUJU brand philosophy: comfort, performance and innovation for your feet

At WARUJU, we believe that comfort and performance go hand in hand. Our philosophy is based on the idea that good support and stability are essential to unlocking your potential, whether in your everyday life, at work or playing your favourite sports. That's why we've created insoles that go far beyond mere comfort: insoles designed to improve your posture, support your joints and maximise your performance, while offering effective protection against pain and injury.

Innovation and Expertise

The design of our insoles is based on cutting-edge technologies derived from our expertise in podiatry and sports biomechanics. Each WARUJU model is the result of in-depth research to offer solutions tailored to your specific needs: whether you're a runner, an elite athlete, a standing worker or simply looking for everyday comfort. We are committed to enhancing the experience of every user through quality materials, dynamic flexibility and targeted support to ensure that our insoles perform, last and respect the shape of your feet.

A new path between comfort and orthopaedics

WARUJU is breaking new ground in terms of insoles: we place our products between traditional comfort insoles (foam or gel) and orthopaedic insoles, creating a range of innovative solutions. Before WARUJU, there was no product specifically designed to direct support while offering immediate comfort, without being orthopaedic. Our insoles are designed to optimise posture and force distribution, providing dynamic support that improves responsiveness and stability, without compromising the foot's natural comfort.

Managing foot instability: The key to prevention and performance

A central aspect of our insoles is the management of the angle of instability between the external rocker (supination) and the internal rocker (pronation) of the foot. This angle, which is unique to each individual, is essential for maintaining balance and preventing pain. When it is too open, the foot becomes particularly unstable, which can lead to pain and injury. WARUJU insoles are specifically designed to limit this angle of instability, reducing the risk of injury and improving overall comfort. Two benefits come together:

  • Improved axes for better muscular synergy,
  • Regular training, for a more linear progression.

Well-being and Providence

WARUJU stands out for its commitment to prevention. Our insoles are designed not only for immediate comfort, but also to prevent pain and protect your feet from the risk of injury. We know that poor support can lead to imbalances that affect the whole body, from the feet to the knees, pelvis and back. That's why our insoles promote optimal alignment of your posture, improving your comfort over the long term. In this way, we actively combat the onset of functional osteoarthritis problems (caused by sporting, daily or professional activities).

For everyone, in every situation

Whether you're an athlete looking for performance or someone looking to improve their day-to-day comfort, WARUJU insoles adapt to your needs. From endurance on the pavement to comfort in the workplace, each insole is tailor-made to give you the best possible experience, whatever your lifestyle. We believe that every step counts and that every movement should be supported by the best technology to give your body the comfort and stability it needs.

French know-how

Our insoles are proudly designed and manufactured in France. We make it a point of honour to use top-quality products, with materials rigorously selected for their performance and durability. This French know-how is at the heart of our commitment to offer you insoles that combine innovation, aesthetics and reliability.

Sustainable production: responsible manufacturing to better serve our customers

At WARUJU, we adopt a lean manufacturing approach to ensure that we manage our resources as efficiently as possible while maintaining the quality of our insoles. We operate on a «one order, one production» model, which means that each pair of insoles ordered is part of a «production train», avoiding costly stocks and reducing the environmental impact of overproduction. By opting for this method, we are able to deliver orders within 15 days, ensuring rapid receipt without compromising on quality. This organisation allows us to concentrate our efforts on innovation and quality control, offering our customers products manufactured to high standards, while limiting unnecessary costs.

Our commitment

At WARUJU, our commitment is simple: to offer you insoles that improve your everyday life, preserve your well-being and free up your performance. Each pair of insoles we create is another step towards a world where your feet are looked after with respect and precision. Thanks to WARUJU, enjoy your activities to the full, in comfort and performance.

Patented, designed and manufactured in France.

All our materials are of podological quality. WARUJU reserves the right to modify its designs as part of its ongoing development. Drawings and photos are non-contractual. Our insoles are not medical devices.
