@dstone124 The boots I make for slalom or trick are sport specific and only similar in looks to the sk8 boots.
In talking with a few "elite" skiers they want next to nothing between the bottom of the foot and the foot bed. In the custom you have only a thin synthetic suede (similar to what your ski gloves are made of) laminated to the composite shell. So, there is no slip no give and they are of your anatomy so no need to tighten them until your foot goes numb. I barely tighten the front boot and ratchet the top strap just tight enough to give a "stopping point" where it begins to puts pressure on the front of the ski.
The heat moldable liners "pack out" leaving hard and soft spots which do not transfer into the ski as a custom does. One of the great thing about the custom is that there is no liner, slip on, slip off, no soggy liner and direct connection to the bottom of the boot.
In the production world, if I get brought on by a major manufacturer, I would like to come up with an "off the shelf boot" and "customs". Customs are the key though as everyone has a little pronation or supination (knock need or bow leg) to their anatomy. I have never seen an ankle that is at a 90 to the ski "straight up and down" like a hard shell and if you look at your feet standing is slalom position you will see where this comes in to play.
Thanks for you input. Everything is much appreciated and taken into consideration. Great input is what makes great products or great products better.....
