Thermo Forming of Boots


SHMR is also known as Super Heat Mouldable Resin. This new technology is used in modern race shoes. The shell constructions is completely different compared with boots using thermo sheets. We are using a spesial heat mouldable epoxy that is combining the different layers of carbonfibre. Race shoes featuring the SHMR-Technology can be heat moulded at ANY spot of the shell, because of the epoxy that is used everywhere in the shell and between each layer of carbonfibre. Another advantage is that the epoxy can be heat moulded as often as you want without loosing its function. The moulding temperature for racing shoes with SHMR-Technology is around 80-90 degrees celsius which is quite low. Another side effect of SHMR is the slightly reduction of weight of the shell.

The following racing shoes featuring the new SHMR Technology:

Powerslide: Double X, Vision, Vision Junior, Infinity, C8, PH9

Core Racing: Vi-Pro, Icon, Triple X2

Thermo Sheets

This „old school“ technology is still common technology in most heat mouldable speed boots. Thermo sheets are thin layers of heat mouldable composites that are placed in between the carbon layers of the shell. Usually thermo sheets have been used around the ankle area of the boot. The boot can be only moulded in the area where the thermo sheet is used and ONLY there, because carbonfiber itself is not heat mouldable at all.

Disadvantage of thermo sheets: The material gets brittle after heating several times and the moulding process is limited. Thermo sheets are NOT used at all in Powerslide or Core Racing shoes.

How to heat mould my skates?

The complete range of Powerslide and Core Racing carbon boots is fully heat mouldable thanks to our superior SHMR technology aka Super Heat Moulding Technology.
Please follow the steps below in order to get the best result.
Our boots can be heat moulded using your oven or a heat gun.


The boot can be heat moulded at any part of the shell. We recommend to keep the frame assembeled to the boots and to fit your boots while sitting. Never put your full weight on the skates during the heat moulding process!

- remove the wheels and open the laces and buckles
- pre heat the oven to 80°C - 90°C
- place the boot in the center of the oven
- leave the boot for about 10-15 minutes in the oven until the shell in the cuff area gets soft


Do not place your foot in the hot boot or you might burn your feet!
Metall buckles or metall eyelets also might burn your finger!
- let the boot cool down a little and test the temperature with your finger before you step in
- tighten the laces and buckles
- make sure your leg is in the correct skating position
- wait for the boot to cool down
- you can use the plastikk end of a screwdriver to press out any part of the boot causing discomfort
- repeat the process with the other boot

You can heat mould your boots as many times as you want if the result wasn’t perfect.


Make sure to keep a safety distance of about 20cm to the upper leather when using the heat gun in order to avoid to burn the material.

Which speed boots are heat mouldable?

Almost all manufacturers offer heat mouldable speed boots. Please ask your local dealer or the manufacturer if he uses so called “thermo sheets” on the carbonfiber boots or a similar technology lie used in Powerslide and Core arRacing shoes. Remember, carbonfiber itself is not heat mouldable. The boot is not heat mouldable without a layer of this material. An exception is the new SHMR Technology used in the Powerslide and Core Racing carbonfiber shoes.

How often can I repeat to heat mould my boots?

You can do it as often as you want with the SHMR technology.

Boots which are build incl. thermo sheets start to get weak after several times. We recommend to heat mould only as often as necessary. It might make sence to think about custom boots if you can not stop the fit problems even through heat moulding.

Why does it take longer time for Powerslide and Core racing shoes to get soft?

The quality of the epoxy that is used for the shell production is the point! The epoxy gets softer at lower temperatures if its quality is poor – therefore the shell gets softer more easy and faster. Most skater think this is good, but the opposite is the case. We use only high quality epoxy forALL our Powerslide and Core Racing shoes. This means that we need higher temperatures to lequefy the epoxy and therefore it takes longer time to soften the shell.

Shoes featuring shells that get soft at really low temperatures might have the problem that they already start to get heatmoulded by accident by just storing the skates in the car with direct sun radiation.
