I recently made the transition from toe clips to clipless pedals , as others have said there is a difference but it's marginal .
Stop start commutes are a pain clipping in .... 'n ..... out ........shaking it all about , but I've been told it gets easier with ( more ) practise .
I did find that straps would rub and eventually make holes in my trainers , but if wanted to pop into Tescos and pick up a pint of milk I didn't look like a reject from dancing on ice .
There's pro's and con's to each of them .
