I picked up a pair of the now discontinued Smartwool Classics in M42. For the record all my other VFF are M41 (KSO, KSO Trek, Trek LS, Bormio, Flow). I've comfortably worn these for 12+ hour stretches at work with no problems. I wore the Classics for part of today and my little toe (only left foot) is burning like crazy! I read on an old post about inverting the heel to help fit which I am trying.
Is this normal with Classics or a sign that Smartwool Classics (I understand the regular Classics have a different sole?) and my feet just aren't meant to be? I had read that the Classics go up a size from KSO fit and the M41 definitely felt too tight in the store. Any thoughts?
Thanks, AndyB, NH.
