I've been having a little trouble recently with my back (had surgery 10+ years ago)... nothing too serious now though thankfully... But my chiropractor said I need a good pair of thick-soled shoes to wear as opposed to thin-soled shoes, particularly when I am going to be on my feet for long periods of time (like at the Louisville Gun show recently for about 6 hours!) I'm obviously not looking for dress shoes but they do need to be appropriate for Dockers-style trousers and button down shirts. Not sure how this applies, but I remember in one of the Jack Reacher novels it mentions his "thick-soled English walking shoes"... I wish I knew more about that... Anyway, anyone have experiences/suggestions they can recommend?
