I own several pairs of McNairy's and they are awesome. Today I'm wearing a derby boot with ridgeway sole and and its one of my favorite shit (or in this case, snow) kickers.
In my experience the McNairy shoes are well built and very comfortable.
I've been close to purchasing walkovers in the past but every time i've handled them i just haven't been impressed.
they don't feel substantial or all that well made.I'd venture to guess that if you were blindfolded and someone put a walkover buck and a bass buck in each hand you wouldn't be able to tell the difference.
