I'm wondering if the heat moldable system really helps on making the boots better fitted on the foot. How did you find the difference after using this system ? Does the skater feel really dramatically better after heating the boot or is it just a better comfort during the breaking time ? Does the oven action have a consequence on the durabibilty and stiffness of the boot ? I wouldn't like to heat the boots and find out afterwards that it actually did reduce the lenght in durability of boots neither the stiffness. Or maybe should I take my boots as they are without any oven action. Need some advices in this area.
