So I picked up a pair of Red Wing boots, and I am guessing they may be Pecos, but not sure. They are not black, but not brown either, more of a mix. In any case, not only no style marking but no size inside either. Is the heel to toe length an accurate measurement of size for these? I am thinking they may be a size too large, but will try thicker socks as they are beautiful color. Can anyone please provide more information on what model these are based on pix provided? The only clue appears to be the number "14" stamped underneath the Red Wing logo on top exterior. Thanks!
