According to Zotefoams' official promotional video on YouTube, the first step of Zoom X is to make PEBAX in the form of a plate made by an extruder, and then put it into an autoclave for foaming with supercritical nitrogen. The next step, according to my personal guess, is to use a machine to cut into the rough shape of the midsole. But what's next? Use a molding tool to create those grooves? Does anybody know the answer?
