It's a stupid name, but you do not clip your toes into the pedals at all. The clip attaches to a cleat at the bottom of your shoe which will be typically positioned at the ball of your foot or mid-sole - not your toes.
I use SPD (i.e. MTB two-bolt cleats) on my road bike and the worst problem I had with clipless was when one bolt had loosened and then fallen out during a ride. I thought that my right foot had a lot of float and when I stopped to examine it, I couldn't get my shoe released at all as it was attached with just one bolt and thus could rotate. I ended up undoing the shoe to get my foot free and after looking to see what the problem was, I decided to ride the rest of the way home (10 miles or so away) and fix it there.
Luckily, I unclip with my left foot (UK, so we're on the left side of the road) so I was fine until I got home and had to take my shoe off again to fully dismount. It's worth checking SPDs for a loose bolt from time to time.
