Last time I got hurt as a result of pedals was when I forgot that I wasn't clipped in and got hit in the shin with my pedal. I ride a short distance - 8 km - especially today when it is -16 (-26 with windchill). I still would rather ride clipped in with my SPD's. The shoes I use though could easily pass as hiking shoes and have recessed cleats so I wear them all day in the office as my regular shoes. Very comfy. So I ride short distances in practical shoes that just happen to clip in. I would never wear road shoes into the office though - I don't even have any. But if someone did, I wouldn't really care. Why do you need to go over 5 miles to wear practical and efficient clothing.
