A grind in which you lead with the soul of the skate and follow with your back foot perpendicular on the rail/curb.

A grind with the front skate in soul position and the back skate perpendicular to the rail or obstacle. A few years ago the Miszou was the trick of choice for transferring from one rail to another, usually to frontside. A topside Miszou is called Sweatstance and reverse topside is called Kind. Miszou means water in Japanese.
