Using normal shoes with SPD M520s
I made the conversion to clipless a few months ago and I am loving it!
However, I only have one bike. If I just want to use my bike to get to a place that is 3 mins away, is it ok if I just use normal shoes with the double-sided Shimano SPD M520 Pedals
I am aware that it is more uncomfortable than using the cycling shoes but for just a 3 min cycle I think it's pointless to have to bring a spare pair of shoes.
Is this OK for the pedals? Will the pressing down on top of the clipping-mechanism make the pedal less effective at keeping the shoe engaged when I do use the cleats and shoes?
