are you on a freestyle team?
why cut them?
if you have to do any of that its not the right boot.
the Lupo is part of the Krypton core line from dalbello.
the mechanics of all the boots are the same sans the hike feature and the soles.
they make softer models, and they are less$. but still fit and function the same way. save the $ on the look of the boot you can't flex and buy another set of boards, go on a trip.
the series (as in all of the kore boots) come in their softest flex mode out of the box. It is possible only in the highest models Lupo and KR Pro to get softer tounges. The pro comes with both, soft and stiff not sure on the lupo, they also work on a rib system in the spine of the boot to change stiffness. This makes it the boot series with easiest and most adjustable range of flex avaialble.
I have had three pair of pros in the last 3 seasons. They changed the boot last year kore2, and made modifications to the shell that made my life easier as far as mods go, expanded toe box width and height, plus navicular punches in the shell and adjusted the stance and cuff alignments. Plus the real intuition liners ( not the BS filler half intuions you get from other companies, make a huge difference.
tons of options here with this boot line, plus all the mods are easy. but you have to get a model you can flex. and if you have a wider foot? they new panterra boot is pretty sweet.
