The burning sensation you feel in your legs after doing wall sits is primarily due to lactic acid fermentation. During intense exercise, when the oxygen levels are insufficient for aerobic respiration, your muscles resort to anaerobic metabolism, resulting in the production of lactic acid. This buildup contributes to the burning feeling in the muscles.
