Cops arrested a protester attempting to throw a shoe at Yemen president Ali Abdullah Saleh outside the Ritz-Carlton hotel yesterday.

Amin Almroot, 34, of Brooklyn, was charged with disorderly conduct for the attempted shoe toss — an act deemed a grave insult in Arabic culture.

Cops say Almroot had crossed Central Park South and was about to take off his shoe to hurl at Saleh, who was entering a car in front of the hotel, when he was detained.

Saleh is in the United States for medical treatment.

Several dozen people attended the protest organized by the Yemeni American Coalition for Change.
