Has anyone done an IM with the K-swiss K-Ona

I just did IMAZ in them, and loved them.  These are my new go-to shoe for both racing and training.  I think they are a great all-around tri shoe.  Light, well ventillated, good drainage (though I'm not dumping water all over myself, but the holes are there) and surprisingly good cushioning. 

I was a bit concerned about cushoning, as IMAZ has a lot of running on concrete, so I picked up a fresh new pair a couple weeks early and did a few runs in them to make sure they were broken in but still fresh.  My prior pair had about 300 miles or so on them, so I could have gotten by with those, but I figured, better safe than sorry.   Feet felt great the entire run.  And that's saying something, as I used to always complain about sore feet on long runs. 

I moved to the K-Ona this year, and I did find that my feet were sore for a couple of months, as my prior shoes were more structured, so there was an adjustment period there.  If you're already running in them, then you should be good to go. 

this is the shoe I used for IM Louisville.  I would 90% recommend these shoes for an IM. 

Just as has been written already, I love these shoes and they are my go to race shoes.  Prior to using them, I thought the drainage was a gimmick but it really works well.  However, the last 5 miles or so of the IM run, the balls of my feet felt like they were being hit with hammers every time they hit the ground.  I suspect that I could have alleviated this problem had I switched to a less cushioned shoe much sooner or had I done a lot more run training prior to IM.  So, provided your feet are ready for less cushion, they are great.
