I've worn Jungle boots for 40 years (not the same pair). These are a little flimsy compared to issue boots.  They quit putting in a lot of tread in the center of the boot so they are thin in the center where the steel shank is supposed to be.<br /><br /> To make these usable,<br />1.  Put on 72 inch  laces so you can let the seam in or out as needed without unlacing the boot each time you take it on or off.<br />2.  Put in some jell soles in them  and on top of the jell soles a standard insert or arch support.<br />3.  Cover the leather in oil or saddle soap so that the leather becomes flexible.<br />4.  BREAK THEM IN by wearing them awhile each day until they conform to your feet.<br />  Overall they cut some corners in building these, but for the price they work ok.
