This is very strange pair of shoes, the soles in general an increase of 4 "long legs." This is four feet long from a very hard material. Of course, the shoes are not designed for ordinary people, but specifically applies to the military field. This is in fact a mine detection for the engineer's boots when ready. The reason why the use of such "legs" from the design, because designers want to make this way step engineering unexploded mines in the accident, the soles of the feet and to increase the distance mines a few inches, making it to minimize injuries . Can not read this small a few inches short Oh. Tested and compared with the traditional engineering-specific boots for this product can be a mine explosion on the leg to reduce the impact of force 4 to 5 times!
