From the very beginning of our company's operation, we have focused on working with the best ski products. 90% of the boots we offer have the capability for full shell molding and liner customization. We are only interested in the best products, thanks to which we will ensure your safety, comfort and durability of the boot selected at our store. Every boot purchased from us has a "lifetime" guarantee for liner molding (most often we carry out this process in the first and second season). A well-chosen boot will allow you to enjoy skiing/snowboarding for up to 10 years before it begins to lose its properties.

The process of fitting this type of boots:

• Individual foot measurements, on matrices and computer scanners.
• Selection of the appropriate size, product selection based on the physical characteristics of the foot.
• Boot fitting, a process fully conducted by our boot-fitter.
• Padding the foot with foam to leave appropriate space in critical places (e.g., ankles, bunions, high instep, etc.)
• Heating the liner in an oven or with a special heater
• Putting on the ski boot with the heated plastic liner
• Fastening the boot as for skiing - the fitting process

Advantages:
• Better fit to the leg
• Greater comfort
• Boots of this type are usually warmer than standard slippers, because the liner wraps around the calf more

MOLDING TECHNOLOGIES:

Thermoformable ski boots: Fischer Vacum
Fischer Vacum – the first boots 100% fitted to the foot
At Kraft Sport store, Fischer boots made in Vacuum Fit technology are available. Vacuum Fit technology enables perfect fitting of the ski boot to the anatomy of every skier's foot, and Fischer Vacuum is the first 100% personalized ski boot.

THE MOLDING PROCESS:

• Interview with the client (we select the appropriate boot model for the skills, individual characteristics and preferences)
• We select the appropriate boot size
• We determine the appropriate position on the Vacuum Fit Station, such as the one in which the skier usually rides
• We heat the boot shell to a temperature of 80 degrees C. (the shell becomes plastic)
• We put on the boots, cooling pads and compression suits.
• We stand on the Vacuum Fit station, connect the suits to the station.
• The boots, under the influence of pressure (previously established), adapt to the shape of our foot, are pressed using pressure.
• The molding process takes about 20 minutes and can be repeated up to 5 times.

Boots can be molded under different pressures, from 100 to 300 mbar, depending on the need:

• 100mabr – Sport
• 200 mbar – Performance
• 300 mabr – Race

Additional advantages of Fischer Vacuum boots:

• Lighter by an average of 15% than regular boots.
• Boot flex is more stable in extreme temperatures (at -20 degrees, it's more than twice as stable as in regular boots.)
• Vacuum station allows the boot to be tilted forward by 14 or 17 degrees depending on preferences
• The shell adapts in the range of +/- 5 mm depending on the anatomy of the skier's foot.
• Fischer Vacuum boots are made in Soma Tec technology.
• Vacuum technology ends the compromise between comfort and fit!

Lining the inner boot with IPS or ICP foam

For a ski boot to be better fitted to the leg, sometimes modifying the shell is not enough, sometimes it's enough to simply modify the liner to achieve the desired effect. At Kraft Sport, we do it as follows. We locate the place where the liner presses on the leg, cut out this fragment of the "boot" and replace it with foam of a different density. It's a simple procedure that can change a lot at the uncomfortable point.
It's also worth knowing that the liner wears out over time and its fit to the leg is no longer as good as in the first season. In such a situation, you don't always have to replace the boots with new ones, only the places where the boot has become too loose can be lined with IPS foam, and sometimes we have the possibility to buy just the liner.

This procedure can solve problems such as:

• Excessive heel lifting in the boot
• Foot movement in different planes while skiing

Methods of fitting ski boots that we use:
Modifying the boot shell by punching.

A procedure used in a situation where the boot shell presses the foot at a specific point. It involves locally heating the boot shell using a special heater or, as in the case of Nordica boots, infrared. We heat the shell until the desired plasticity is achieved, after which we expand the given point to achieve full comfort.
The shell of new and used boots can be punched.
It often happens that imperfections in the fit of newly purchased boots only become apparent on the slope, when the boot is cold and the shell is stiffer than during fitting in the store. Sometimes, however, it's already known during the purchase of the boot that changes to its shape will be required. This usually happens with people with less common feet (wide foot, additional ankle bones, deformed foot after injury, bunions, neuralgia resulting from tight boot fit, heel spurs and others). Shell punching is also a good solution when the boot we want to buy fits almost perfectly and only requires a small, point correction.

Boot shell milling

It involves local, delicate cutting of the shell to create the appropriate space for those parts of the foot or calf that are pressed. Shell milling is used when the boot presses the foot at a specific point and we cannot adequately heat and shape it.

This method of modifying the shell can be used interchangeably with shell punching or even simultaneously, but usually shell milling is used for very small corrections or where punching is not possible. It should also be known that the thickness of the ski boot shell is not uniform everywhere, and the choice of the shell shape fitting method also depends on this.

Thermoformable Sidas insoles

Personalized SIDAS ski insoles are recommended for every skier, because during skiing there is a lot of foot strain. Their even support has a positive effect on joints, foot circulation, stability and transmission of impulses from the leg to the boot and further to the ski.
Ski insoles available on the market come in several variants depending on the customer's needs, we form them based on the client's footprint.

The process of preparing insoles:

• Foot analysis on a podoscope
• Selection of appropriate insoles according to the client's requirements (hardness, stiffness of the insole)
• Taking a foot impression
• Heating the insoles in the oven to make them plastic
• Forming the insoles and cooling them
• Final grinding of the insoles so that they fit the boot and have a regular shape

Benefits of using Sidas insoles:
• The foot is evenly supported, which protects our joints from excessive strain
• We guide the skis more precisely because the foot is better stabilized and the perfect mapping of the shape of our foot makes initiating a turn faster.
• The insoles largely prevent the foot from moving in the boot, thereby reducing the risk of abrasions, frostbite or pressure marks.
• Proper foot positioning has a positive effect on other joints - knee, hip, spine.
• Comfort in the boot is incomparably greater
• People with orthopedic problems often feel pain while skiing resulting from e.g., flat feet, bunions, hollow foot and others. Sidas insoles significantly or completely reduce these unpleasant sensations.
• Sidas insoles can also be worn in regular everyday shoes.

Therm-ic heated ski insoles

Frozen feet on the slope are no longer a problem, at Kraft Sport we have insoles with a heating system. The insoles are heated in the front part where the feet freeze the most, so we immediately feel pleasant warmth from the beginning. These insoles are equipped with batteries connected to the insole by cables, which are routed between the shell and the liner so they don't reduce the skier's comfort in any way. Therm-ic heated ski insoles, depending on the type of batteries, heat for up to 8 or 6 hours of continuous operation. Such a solution is currently the best solution to the problem of freezing feet while skiing, and the latest battery model has Bluetooth which allows temperature regulation from the phone.

Volume reducers

They are used when there is too much space in the boot, it's a simple procedure to better stabilize the foot in the boot when it's too loose. The reducer is placed under the insole in the liner. The liner compresses over time and there is more space in the boot than during the first days on the slope, then a reducer with a larger volume can be used or the liner can be replaced with a new one.

Boot dryers

To take good care of your feet and ski boots, it's worth getting good ski boot dryers with an antibacterial option. The problem of freezing feet often results from not fully drying the liner. It's best to do this by removing the liner and insole and placing a dryer in it. Dry liners provide better hygiene and slow down liner wear.

Shin protection

Epitact, or special reusable gel patches, are applied to the shin at the point of greatest pressure of the leg on the boot tongues. The pressure is distributed evenly on our leg, avoiding pressure marks, abrasions, wounds. Epitact can be used up to 30 times. Just rinse the patches under running water after use, dry them and they're ready for reuse. They are made of a material that has very delicate self-adhesive properties, effectively sticking to the leg and can be easily and painlessly removed.

You need to know that your feet are:

• THE FOUNDATION
They are responsible for maintaining the correct body posture, responsible for stabilization, movement and cushioning. The mass of our body rests on just a few dozen square centimeters.
• COMPLEX
They consist of 28 bones, 33 joints, 107 ligaments and 27 muscles. During exertion, the cushioning system loses its effectiveness, the foot lowers and deforms.
• ALIVE
They react to many stimuli, when repeatedly loaded they can even change their length
• SENSITIVE
Feet are heavily exploited throughout the day and are like a sensor whose sensations affect our body, unfrozen toes can cool down the entire body
• UNIQUE
The unique shape and characteristics of your feet (length, width, height, toe arrangement, foot arches, foot muscle efficiency) create the need for individual adjustment

Sidas insoles are created precisely to take care of the foot in an individual way.
It's worth remembering that the boots we buy are mass-produced and everyone's feet are individual and unique. So the question is, should the foot adapt to the boot or the boot to the foot? We believe that fitting the boot to the foot is the right way, that's why we offer our customers Sidas insoles.
Sidas shoe insoles create the optimal connection between the foot and the boot. Using these insoles, you can feel exceptional comfort because the weight of our body is distributed evenly. We also reduce the risk of injury because the foot is more stable in different planes (longitudinally, medially and laterally).
By using shaped insoles, you also protect other joints: knees, hips, spine. The insoles cushion well and the supported foot works better, which affects the functioning of other joints when performing various movements.
Sidas offers various types of insoles: insoles for ski boots, running, general sports, trekking and for shoes with less volume or everyday insoles.
