Toe clips with straps are a pain in the neck if you're wearing walking or running shoes with wide toe boxes and thick grippy soles. In other words, pretty much any walking/running shoe that's comfortable to walk/run in.

Toe clips were designed for use with cleated smooth soled shoes with very stiff soles, often with steel or other inserts for stiffening. Touring shoes were less rigid, pretty similar to bowling shoes with more rigid soles. Smooth leather, no grippy rubber edges to snag on the pedals, toe clips and straps.

If you have some dress type shoes (be careful not to scuff them) or casual leather shoes like moccasins or deck shoes, try those around the block. You'll probably find them easier to slip in and out of toe clips.

There's at least one company that still makes a nylon or plastic cleat that can bolt to new style clipless shoes without the recessed insert. I considered those for my Scott Pro Road shoes, which are similar in styling to my old Detto Pietros. But, nah, I went with Look delta cleats and pedals. They work better. No need to reach down to cinch or open a strap quickly in traffic. Less constriction on the toes -- to be effective the straps need to be cinched down, which can interfere with circulation to the toes.

But if you prefer to walk and ride with the same shoes, get SPDs and mountain bike type shoes. Most of my cycling friends who started with road type shoes, cleats and pedals switched to mountain bike pedals and shoes. But I seldom ride my road bike in traffic where I need to unclip a lot or walk, so the Look and similar cleats/pedals are fine for me. I still prefer platforms and comfortable shoes for casual rides, errands and combining riding and walking.
