I'm not really a fan of zips on shoes, but the zipped boots in the video look cool.I found video about training your engineer boots to make it creases in certain way, japanese people are very thorough with everything
Apart from that, they don't do anything different to what happens when you wear them normally. It just doesn't work if you only wear them once a fortnight.
I just take my new boots for a walk around the forest (5 km), ideally when it's moist, and then they don't look new any more
