On the first view they probably just look like regular jungle boots.
This is a replica of US jungle boots, how they were made during the Vietnam war era.
The classic Jungle Boots as issued by the U.S. Army in the 1960s. Pike Brothers have reproduced early pre spike protection boots without the metal insole. So these are lighter and more comfortable to wear than the later models. They even reproduced the first sole pattern from that time, which can be told by that hex like shape in the middle.
