Had Kennetreks but just couldn't deal with the heel blisters any more. Tried the Lowa Tibet Hi's this year. Steep climbs and descents, plenty of side hill, deep snow, creek crossings... all good and very comfortable as well. I'm in between sizes so mine are a half size up and just slightly loose, so I wear a liner and a regular cold weather boot sock (make or blend doesn't seem to matter). Probably the best lacing system of any modern boot which will help to avoid jammed toes or laces relaxing to the point that you need to re-lace. Laces are just the right length and that never happens! Roomy toe-box (finally) which IMO, is very important for side-hill and downhill. No leaks. This boot is "built for purpose". Bottom line... I wasn't thinking about my feet.
