both:
-stiff
-similar price
-made by line
-heavy
cronic crypt:
-sidewall
-92 underfoot
-all mountain
-non semitrical
-a little more durable
-rips up everywere
stepup:
-skate deck
-85 underfoot
-park oriented
-semitrical
-a little less durable
-dosent carve the best
my recomendation:
-if u like skatedeck, and will only ski park, and no pow and little all mountain- get the stepup
-if u like sidewall better then skate deck, ski some all mountain but still a lot of park- get the chronic cryptonite
