At the end of last season on my one binding the semi-circular black plastic piece that provides friction to prevent excessive heel movement popped off. It looks like the three prongs that fit into the metal holes wore down. I can easily put it back on however it pops off when pressure is applied. Has anyone else experienced this? I thought about rigging it back on with glue but I'm worried it will just break off again. I could see if Look will warranty it considering I purchased the bindings in 2011. More or less I just wanted to see if anyone has had this happen and if there are replacement pieces I can acquire or if going to Look is my best option.
