Vivobarefoot can be narrow and &#34;flat&#34; in the toe box part. Trail Freak is an example. I own two pairs of Vivobarefoot, Evo Pure, one in blue, the other white/red lining.  I love Evo Pure, because it makes my feet look &#34;narrow&#34; while providing ample room in the toe box area. I ordered them in the same size, but Trail Freak came out narrow and uncomfortable as soon as I put them on. So sorry.
