I've been wearing original long-tongue sambas for about 15 years, no problem. For some reason I decided to try them and I really regret it. I even paid them extra. They squeak horribly with every step I take, both shoes squeak very loudly. I've tried wearing them for long walks, runs, etc., but the squeaking won't go away. Maybe I'll try putting duct tape on my tongue and see what happens.
