I'm pretty sure. They are the exact shape of the J Bar. If they are not supposed to go there, I don't know why they would go through the effort. I have 2 pair of 2012 One's and had a pair of 2011 Relik's and never had a problem with them not staying.
If I remember correctly, the J Bar and the section in the boot where they attach are both the 'hook' side of velcro. They don't really grab each other, but rather stick together with pressure. Once you get them down there, just apply some pressure and they will stay, especially once you put your foot in the boot.
