Are you wanting to display, wear or both?
The best way to fix the collar for a display is to simply add some card board tube that you split down one side. If wearing, then I would have to say that that velcro thing we've seen on the V2s is the way to go as that will be the only thing that will hold the strap on place, because whilst you walk, it tends to slip down and the collar loses that cool shape.
Unless you feel comfortable with a full tear down and build up, I would not worry about the laces. I mean those holes annoyed the hell out of me with my pair right up to the day I sold them. Not an easy fix.
I will wear them. Well I'm planning to go to conventions with them.
Should I maybe glue the foam protection on the back to the shoe? So it will make sure that the strap holds in place?
I've actually another pair of MP shoes. I will try to change the laces on this one first and see how it goes. It's not that i'm incomfortable with them... but, it's not really screen accurate so it bothers me a bit x)!
It's only the slimming toe that is quite scary, I kinda want to do it, but I would be REAALLY annoyed if it does not work out. I've seen a tutorial on youtube, and you have to be really meticulous...
I was wondering too, is there any chance to get the foam back from the chinese replicas? They look to be more accurate x)
