I have both but have only skated the janoskis not the kostons yet. The kostons are more comfortable but the janoskis skate great and I am on my 3rd pair of those.

…umm in what sense? which is a better looking shoe? which is a better skate shoe? hows this battle suppose to be?

Janoskis need a air bag on the foot bed of the shoe and a better structured toe cap underneath the actualy toe so it doesnt mess your feet up all bad. Koston wins by K.O.
