In the process of creating a customized ski boot the raw materials are both thermically and mechanically formed. At the same time it is important that this forming process does not result in any impairment of the material´s structure and strength, i.e. there is no loss in material quality. Only very few, high quality materials are suitable for such processing.

We carefully select our materilas and continually test their quality and characteristics. In this context we work with leading manufacturers such as Lange and Salomon.

Your feet and legs are surveyed up to the knee by means of modern scan technology and used to create a virtual 3D computer model. Our ski boot technicians can use this model to determine the precise dimensions at all key points. In order to be able to construction individually optimized ski shoes, the individual skiing specifications and the customer-specific needs and requirements are determined and entered into our system.

The data from our ski boot specialists is evaluated at the Munich bootmaker´s workshop. An individual wooden last is created by skilled craftsmen and the outer ski boot shell is carefully matched to your foot form. This requires a lot of experience and systematic knowledge of the art of boot making. Finally the detailed finishing work is painstakingly performed so that the ski boot is a perfect fit and offers complete comfort.

Depending on individual needs and requirements, the inside of the shoe can be foam lined. Once the foam hardens a perfect match is created between the foot and the ski boot, thus ensuring optimum force transmission.

The finishing touch is provided by the insole that has been especially designed and produced for you. It guarantees optimum weight distribution and takes the load off your feet.

Our team is continually searching for the best running shoe models on the market. These are carefully selected according to predefined quality standards and properties, and tested accordingly - because your feet should be able to carry you many miles.

Thus our credo is not to deluge you with a baffling variety of running shoes and brands, but to offer a focused selection of the best current models. From this selection, our team identifies your optimum shoe and gives you detailed advice in relation to your requirements.

Pronation and the foot form are decisive factors in determining the ideal running shoe.

With data from our pressure measurement plates we can statically analyze your feet to determine where and how they are loaded and accordingly draw initial conclusions about your leg position.

The dynamic analysis is at least equally important. To this end, our running experts observe your running sequence on a specially created test running track. Each single phase of the movement cycle from setting down and cushioning until the foot touches down again can be exactly analyzed in slow motion and evaluated.

The joints, tendons and ligaments are subject to heavy loading during running - existing, usually as yet unnoticed misalignments often lead to pain or even serious injuries.

Our orthopedic shoe technicians design and make your individual running shoe insoles, which cushion and guide your feet and provide support at the required points in the longitudinal and transverse arches. The properties of the insoles are precisely attuned to your feet and perfectly matched to your running shoe.

Your feet feel great and thanks to the increased comfort you can now completely concentrate on enjoying your running and achieving your sporting targets.

During a round of golf your feet may cover many miles. It is therefore of decisive importance that the shoes are still an optimum fit even after several hours of wear, that they support your stance, are comfortable and do not produce any pinch points.

With golf shoes, it is not only the shoe size that matters but also the width. With our 3-D measurement technology we can find a shoe with the optimum width, form and performance for your feet. Furthermore, the renowned golf shoe maker Footjoy has given us, in a world exclusive, access to the fitting data of the MyJoys models. We are able to compare these with the data obtained from the measurement.

Distance and Precision.

New at our Munich flagship store is the golf tee-off analysis. The optimum position of the body's center of gravity plays a decisive role in generating a powerful swing. With the aid of state-of-the-art technology we are able to determine the location of your center of gravity and optimize it by means of the golf shoes and of custom-made golf insoles.

At ERTL/RENZ we produce special golf shoe insoles that are perfectly adapted to your feet and body posture when swinging the club.

In addition to a perfect fit and superlative comfort, these insoles encourage the wearer to adopt a healthy body posture and enhance stance and stability when swinging. Thus the custom-made golf insole can exert a corrective effect, optimizing the position of the center of gravity when tee-ing off.

Our specialist staff will help you to find your optimum model: in a detailed discussion we determine which characteristics your perfect boot should have - whether comfort or performance, with narrow or wider soles - we guarantee that we will find the correct boot.

A hiking boot should primarily offer the foot firm support and ensure a sure footing. At the same it must be flexible and comfortable enough so that no pinching, blisters or aching feet are produced, even after long treks. We measure your feet with our 3-D scan technology to find the perfect fit for you and compare the dimensions with the available boot models.

This means that an optimum fit and the highest degree of comfort are assured.

Furthermore, our team will advise you about suitable materials and the characteristics of the boots that correspond to your requirements.

The perfect hiking boot model is usually only half the story when it comes to avoiding blisters, pinching and joint pains.

Everyone subjects his feet to loading in different ways and everyone has his own distinctive gait. Accordingly, the correct footbed for each individual plays a crucial role. After investigation of your foot posture and your movement sequence, our orthopedic technicians create special hiking boots insoles that perfectly match your anatomy.

These act preventatively to forestall complaints due to loading and with their shock absorbing properties protect knees, hips and the spinal column. The breathable insoles are precisely matched to your boots and form a perfect unit with them. What is more, the insoles can be easily and conveniently removed so that they can be dried, cleaned and conditioned as required.
