Ski touring boots or alpine ski boot a never ending battle of compromise or a great reason to buy two sets of boots?
A few years ago it was a lot easier to tell the difference between AT boots and alpine boots, for a start all the people in AT boots had long hear, beards and smelt like scroggen. These days the boundaries between categories of ski boots be it AT or race have become very blurred. Brands love to offer the quiver boot as with skis and although some of the ski boot manufactures are getting close to the perfect boot their will always be compromise.
As close to perfection as some of the brands have come I can’t get away from having two sets of boots, that’s an alpine freeride boot and a light weight AT boot. The comparison in skiing performance might not be massive but taking skis and bindings into account and things become worlds apart.
The most important factor and the biggest difference between ski touring boots and alpine ski boots is the stiffness or rigidity of the plastics used. AT boots sacrifice rigidity and stiffness in the shell and liner for weight, its that simple. Many brands are attempting to over come this issue with very clever shapes and structures used in the moulding of the shell to add rigidity and stiffness. Rigidity and stiffness in the boot shell and liner transmit the movements of your leg and foot with more power and accuracy they can deal with higher speeds and increased force’s. At the top of this tree is the race boot, not built for comfort though these boots are built for speed. TBC
