They finally got it right!  This is what minimalist should be.  Just thin, smooth, light, plenty of space in the toes and very flexible.  These are essentially like a thin second skin.  I ran three or four miles right away - no break in required.  As another reviewer noted, they do run a half size large - I found the 9.5 fit best when I normally wear 10.  Note, these are really minimalist.  Excellent design and quality!
