The Inferno Heat is built on the same 98mm last as Tecnica’s high end race boot, but comes in a much friendlier 100 flex.  Even with the softer flex the Inferno Heat performs very well due to the narrow last, high end plastic and mono-injected shell. It comes with great features like a shock absorbing boot board that make the cliff drop a little easier to stomp. This is a great ski boot for an intermediate to light weight expert skier who has a narrow to slightly narrower than average foot. The Inferno Heat from Tecnica fills a much needed void as there are few narrow fitting and easy flexing boots available. The Heat boot is more than capable of performing well in all terrain.

This men’s ski boot is measured in US sizing.  The easiest way to determine what size you should purchase is by taking you regular shoe size and decreasing it by 1.  For example if you wear a size 11 shoe, chances are you are a 10 in this boot.  This simply math works almost all the time.  It is extremely rare that a skier wears the same size ski boot as regular shoe.  Occasionally a skier may wear a boot that is 2 sizes smaller than their shoe size, but typically this skier already knows their size.
