Shimano

I treated myself to some Shimano shoes and pedals.  I must be mad, I spend ages just trying to get my shoes to clip in!  Eventually I get one foot in, pedal one footed and then manage to get the second one is, whoppee.  But, when it comes to stopping, nightmare, I cannot unclip fast enough, so I just fall over, I am covered in bruises on my legs and ribs.  Thankfully I am testing out my pedals on the grass footpath borders, so I get a reasonably soft landing when I fall, and I am not in the path of oncoming cars.  I am going to have to put my old pedals back on or I cannot ride. I wonder, do they make stabilisers for racing bikes?
