before you go splashing out money on shoes and pedals…..
and assuming you are running shimano spd’s..
Get yourself a set of Shimoan SH-56 cleats (£5ish on ebay)
These are multi-release and are easier to get disengaged than the standard SH-51’s.
If you have the tension set right, you can get your foot off the pedal just as fast as you can coming off flats.
