Having worn these for a few days,  I'm noticing some things that I'm disappointed in.  I like the shoes overall, but they aren't as nice as the previous version.  I wear these eight hours a day at work, as a teacher.  I'm on my feet a lot, and I'm a big guy (275 lbs).

The good -

The shoes are as cushy as the Kahana 5s, which were the cushiest I'd ever worn.  Since getting the new pair, my knees and ankles hurt less at the end of the day.

The soles remain the same, with excellent grip.  I can walk through puddles on linoleum floors without slipping.  I'm buying these for the grip more than anything at this point, as I tend to have water everywhere all the time and slipping is a major issue.

The price is very reasonable, which is a good thing.

The bad -

These have a lot less ventilation than the previous iteration.  My feet have been getting hot and sweaty much more than before.

I like the previous color scheme better, but that's a minor quibble.

These run smaller and narrower than the previous version.  I had to send back the 10.5s and get 11s.  I have 4EE feet, and even the 11s feel narrower than the 10.5s in the Kahana 5.

The tongue seems narrow.  It has to be perfectly centered or my socks show through.

In short, for 55 bucks, I'll wear these a few months while waiting for the Kahana 7s to come out, and will hope those are an improvement.  I wish I could find the 5s in my size.
