I had the original Vivobarefoot Ra's, and I loved them.  They had a couple fit issues though, mostly in that they were too wide for me.  The Vivobarefoot shoes are supposed to be wide so that your foot can spread out, but the original Ras were really really wide.  The newer ones are a tad narrower, so if you were really happy with the originals, you won't be so happy with the Ra IIs.<br /><br />Overall, the Ra IIs are just okay.  The build quality of these (might just be the SofA ones) is not very good.  The insole has wrinkles in it and the outsole has already seperated from the upper.  Its held on by the stiching, so its not gaping off, but that shouldn't happen in the short time that I've owned them (about 2 weeks).  The heel is also constructed funny, I think it might be a design issue though. It slants really severely to the front of the shoe as it comes up from the sole, so it really digs into my heel.  I've taken scissors and trimmed the seam, maybe that'll allow the heel to stretch a bit more.  Or maybe I just ruined my shoes and made it so I can't return them.
