Went clipless at age 58 , Look pedals , Shimano road shoes , & Look Delta cleats - took maybe a 1/2 hour to get going with them and then just practice and fine tuning the pedal tension - I'm currently riding with total Look Keo , pedals and cleats but also have Shimano SPD-SL pedals and cleats - disengaging is about the same with each but for me I give a slight nod to the Looks for clipping in .

Good Luck !!
