I do like my drop kicks, and do not feel that they are a "low end" boot. I do however, wish that they came standard with metal buckles despite the small weight gain. The piece that broke was actually the pin in the little push tab that allows the buckle to slide, which would probably have happened with the metal buckle as well; the buckle system is what I think needs redesigning, the shell I really like despite its redundancy.
Also, I am not "complaining", I would buy a replacement and be on with it but I cannot find them anywhere. The purpose of this thread is to see if anyone knows where I can get them, or if the top buckle would work instead.
