Worth a try....I think it is great that some people here can get by with a pair of $40 cheapies from Wally World, but I do not think you are doing any favours to your feet in the long run if you go that route, especially if you are standing all day tugging brush or up a tree in spurs. Not saying you need to spend $500 either just find something that works for you.
Ever see a specialist to get fitted for a pair of inserts uniquely designed for your particular problem? Again not cheap, but maybe worth the $$ in the long run. Mine address the fact the joint in my right big toe is non existant, and hence have a steel plate under that area, and to even out the gait/effort the left is identical. Wear these only in dress shoes and sneakers as my boot have stiff soles and steel plates that more than do the trick. A pair of Danner "Fort Lewis" boots I got in the Army came with a plastic arch insert which I did not find too bad...though maybe with flat feet it would be painful.
I have a pair of Viberg Lineman boots as well, as per Clearance "Steel toe, steel shank, very heavy thick soles, Vibram and then layers of leather". Hope the Baileys work for you as nothing is worse than painful feet, been there.
