lets clarify some terms here

toe clips are the cages that attach to the front of the pedals
into which your feet go

most toe clips are used with straps that can adjust
to tighten or loosen the fit of the toe clips on your feet

some toe clips are designed to be used without straps

toe clips are usually used with redular shoes
but in earlier times there were pedals and toe clips
designed to be used with cycling shoes with cleats on the bottom
mainly used for racing

the other style of foot attachment
are called clipless pedals
because they attach your feet without the use of toe clips
these are also sometimes called clip-in pedals
these are always used with cycling shoes that accept
a cleat on the bottom

of clipless or clip-in style pedals
there are two main types

road pedals
which use a large cleat and a rigid soled shoe
that is very difficult to walk with

and mountin bike or touring pedals
that usually use a smaller cleat
that is recessed inside a more normal treaded sole
these shoes are designed to be easier to walk with
