There ya go! Stiffer soled shoes and shoes with stiff uppers will be more comfortable in clips. If you hate 'em after a 1000 miles, you can always change out for clipless. I started road biking long before there were clipless. Clips can make your feet cold, can be dangerous, and can make your little toes hurt. Other than that, they're great. When you use them, tighten the strap and secure the end on one foot. On the other foot, just pull the strap tight, but don't secure the tail. It's quick to reach down and loosen the buckle when you see something coming up that might make you put a foot down. Over a few hundred miles, the pedals, if they're cage pedals, will wear grooves in the bottoms of your shoes. This will help keep your foot in there, but will also make it harder to pull your foot out. I used to cut in grooves, once their positions were well marked on my shoe soles.
