I am not really sure of surname of this guy, so let’s call him just Marek. Today this man from Poland made a short video on his new obstacle called alf ledge white wave company. It is some kind of marble, just a normal curb for fingerboarding. Marek has really insane technique and style, all his tricks are really hard. For example ss inward heel 5-0 ss inward heel out or flip underflip nosegrind. Kinda impossible.
