the picture looks like desert boots to me -- i cannot make out any drainage holes like on other jungle boots...I think you could re-sole the Austrian army version easily, because it's sewn, not glued together.
Perhaps it's worth to try them ?
strangely no leeches around here (not that i'm complaining ) --- the locals didn't even know what i was talking about when i was trying to find out the (local) spanish word for them...Jungle boots tend to have metal mesh covered drainage holes. Jungle sand gets everywhere, drain holes or not. Ditto leaches.
