You will know if they are intended to be tucked in or out. A vast majority are to be tucked in, and a select few like Dainese will be out.
I have a RS Taichi EVO Viper and it will not fit OVER the boots. It was designed to fit UNDER the boots. Is it better than over the boots leathers?...I don't know. I have done my research and spent my money as needed. Dainese has outstanding products, shoot I have a Dainese Jacket...which is exactly what I wanted in an every day leather jacket.
