Back in the 1980s people used toe straps. Bike stores sold shoes designed to work well with toe straps. I bought a pair and still use them today. Last year I tried clipless. I kept them on for about 6 weeks because I wanted to make sure I became fluent in clipping in and out in all situations and learned how to best use them. They worked fine. But the didn't work any better than my toe straps (with my toe strap designed shoes). So I went back to toe straps because the shoes for the toe straps are perfectly comfortable off a bike whereas the the shoe with the spd was not comfortable off a bike.
