Replying to Fulltilt Hot dogger -> Salomon Kaos

So i've been skiing on my hot doggers for like 2,5 seasons now and it's time to buy a new pair of boots. My feet have grown some width, so after like 5 hours of skiing it starts to hurt, but not in a way that it would affect my skiing and I don't even usually ski that long.
 I've tried the Salomon kaos boots on a couple of times and I kind of like how they feel, not too sure about them since I love the comfy feel of my fulltilts. New fulltilts with the outershell molded would cost about 260$ more than the Kaos boots, so I'm thinking of buying them.
Help me out guys. How are the kaos boots compared to fulltilts and is it really worth it to pay 260$ more to get a pair of TOM WALLISCH pro models. I've loved my hot doggers except that they smell really really bad and my feet sweat in them like crazy.
