Here is the story, I went to my local pro shop to have new tuuk holders installed. After I got them back I had nothing but problems loose rivets, the rivets destroyed my footbeds because they weren’t flattened, loose blade, my skates sounded like tap shoes. I dropped them off and picked them up many times and still had problems. I decided to figure out a way to do it myself. So at anytime I wanna swap holders all I need is a 2.5mm Allen key, I did not alter the boots at all , I just removed the rivets and installed the silver flat tee nuts. And mounted with stainless steel Allen bolts with brass washers.
