alright, i ahve owned both of these boots and hated one pair loved the other....  
kreations, nice boot for park skiing.(period) they suck outside of park, i was gonna buy some boots adn it was between kreations or kaos, i figured well im spending alot anyways why not save 100 bucks and get a cooler boot, well i ended up buying the kreations, in a 27.5 (i just recently got my boots fitted and im a 25.5 so you could imagine the shinbang) well ya i had horrible shin bang and what not, then one year later i end up buying the kaos, its soooo much better. besides the smaller size its a heck of alot better, between the draw string, the "slick back", the flex and the nice cumfy liner, its deffinatly worth it to buy the koas, and now that i looked back i realised two things (listen carefully) one, never order off the internet unless you have allready tried on the boots and had them fitted at local shop, and two its worth it to spend an extra hundred or 200 dollars on a really comfortable ski boot than it is to save that money and have uncomfortable feet, cuz that makes your whole skiing experince miserable. just my 2 cents
