I've been doing pretty much all my shorter runs now in the Inov8 Roclite 295 shoes.  I'm very much liking them.  At this moment, I plan to run in them tomorrow, but it'll be a last minute decision I think.  The shoes are different, especially when you just put them on and sit there in them.  The insole reminds me of my Specialized Body Geometry cycling shoes, especially the earlier generations where there was a pronounced bump under your metatarsal area.  But, as soon as you hit the trail, you don't notice it, and in fact, the shoes just seem to fit me really really well.  They are more minimalist compared to the Brooks Cascadia, but so far, all I've been able to notice is that I feel more of the trail under my foot - I haven't noticed any particular muscle pain or other side effects that you sometimes hear about with more minimal shoes.  This is partly why I'm ready to go try them on a longer run (longest in them to date has been 6 miles).  Should be interesting.  I will also be interested to see how my legs fare having done the 9 miler on Thursday.
