haven't found any boots that can do the NT conditions . Run the cheap Merels or Keens, light weight and expendable. Bowhunted the swamps for years in booties or volleys.
Tried some of the expensive boots and ruined all of them so stuck with the cheaper options.
Just retired from the NT after doing 35 yrs up there. Darwin, and Jabiru mainly.
Great place and hunting. Im not missing the heat.
Cheers Mick
