The power benefits of toe clips are exaggerated, but that doesn't mean that they're not without purpose.

The main purpose is to hold your foot in the right place on the pedal, and ensure that it doesn't slip out of position or off entirely.

Of course, they're a mixed blessing, and can be a nuisance in urban riding where you have to set a foot down every few blocks. That nuisance level depends on how used to and comfortable you are using clips. I have them on my commuter because the added security outweighs the drawback of getting back in each time. But I've been riding with toe clips (and later on clipless) for almost 50 years, and the last time I had a problem was something like 49 years ago.

Whether to use them is strictly a personal decision, and probably turns on the riding conditions, and your comfort level using them. So, I'm not going to advise either way, but I will remind you that any decision isn't binding, and you can change your mind at any time.
