One of the flaws for having clipless pedals is that it's hard to walk in. You shouldn't be walking around in them because it wears out your cleats.
I suggest getting cages and straps, for those commuting around town days, and switch it up to clipless when you're actually cycling, and nothing else besides walking into the store to buy a drink or something.
For clipping out, I had a hard time at first, but I unclip my pedals as my cranks are half rotation from a complete stop.
For clipping in, you just get the hang of it as you're riding.
Just like cages and straps right? Not alot of people can get their foot in the straps their first time.
