 People in the Song dynasty never left their homes barefoot , and always had some sort of headgear on . Shops in the city specialized in certain types of hats and headgear , including caps with pointed tails , as well as belts and <unk> . Only Buddhist monks shaved their heads and strolled about with no headgear or hat of any sort to cover their heads . For footwear , people could purchase leather shoes called ' oiled footwear ' , wooden sandals , hempen sandals , and the more expensive satin slippers .
