Back your shimano’s all the way out. Then turn them in 8 clicks. Next, pump your tires up high and ride all week on the road in the evenings after you get off work. Clip in, clip out, clip in, clip out. When you feel like you are getting more confident, ride with one foot clipped in and the other hanging. Switch after a little while, then turn them in 4 more clicks and lower your tire pressure. Go ride a Mtn and enjoy your new pedals.
