Question: Is it possible to use regular trainers/shoes (i.e., withou cleats) with clipless pedals?

A friend of mine mentioned he does this all the time. However, I cannot imagine how this would work. Surely the area of grip would be far too small to get any kind of purchase on the pedals.

We both have [Shimano PD-R540 SPD](https://bike.shimano.com/en-EU/product/component/tiagra-4700/PD-R540.html) pedals.

Answer: 
Yes, you *can* use them with normal shoes, but as you predict, it isn't very comfortable, especially if your shoes have thin, flexible soles. Also, there's a risk of your foot slipping off, particularly in the wet.

There are various options to temporarily convert clip pedals into ordinary flat ones.

UPDATE: I use Fly Pedals now when I want to convert my clipless pedals into regular pedals. They are made of machined aluminum, light weight, and lock together so you can put them in your pocket. They cost $50 plus cleats.

[This company (started on Kickstarter)](http://anykicks.la/) makes flat platforms with straps on top and cleats on the bottom. They convert clipless pedals into toe clips. A pair runs $55 without the actual cleats.
