I got excited about these and bought a few pairs a couple years ago.  Now, either my feet grew or I just screwed up, but these things are too small for me.  They've been sitting in reserve for so long that I can't return them. 

 Honestly don't know the name of these because they don't sell them anymore, but they're lighter weight than the Konseal FL2.  These are size 11.0.  Lightly worn.
