Update to this
http://sharpcraft.com/content/node/87 post on my new Adidas ClimaCool Cardrona shoes.
I was experimenting with Clif Bars (good) and PowerBars (evil) in between swimming & running so stomach cramps turned my two-mile run into a 45-minute 1/2-mile run & 1.5 mile walk/run/roll-in-a-ball extravaganza. Then a few hours later I did a 20-minute family walk with my beautiful bride and wonderful daughter. That's enough to get an initial report.
Hot Spots: I have a few hot spots - one on top of each foot where the laces may have been too tight, two on left toes, one on a right toe.
Arches: My arches have a little ache. I don't think I need planter fasciitis so I'm going to look at the arch supports and compare them to my other shoes.
Midfoot Striking: I didn't have any problem with the shoes trying to change how my feet hit the ground, so that's good.
Heel: The heel feels like it grabs the ground like a magnet - solid enough that I would be worried about twisting a knee if I was a heel-striker. It might have too much traction for some uses.
I'm used to just putting on the shoes and that's it - running shoes don't normally need a break-in, do they?. So we'll see how it goes with the hot spots. I used to have a pair of Asolo trail shoes. They felt like boards on my feet for a year or so. Then whatever caused my problem finally wore out and they were great after that, until the eyes pulled out and the leather wore through on the toes.
