Something I only recently learnt about Shimano SPD cleats. There are essentially 2 types. The standard single release ones (SH51 SPD) that most will use as they tend to ship with pedals, and the 2 way ones (SH56 SPD) which are much, much easier to release
forgotten that was just about to go root in boxes for some for mrs antigee’s new shoes – oddly her old ones are unpainted and seem to be marked SH51 (I prefer SH56) – now I thought the single release ones came in black to differentiate without squinting at the markings? love the way shimano always marks part numbers – so civilised
as to learning to use my advice that I’ve found worked with those not willing to try due to fear of cocking up is if not got one beg the loan of a turbo trainer and in 30mins or so will have the hang of it – or spin bike at the gym – lots of these have shimano spd compatible pedals – though may need to try a couple of bikes as sometimes a bit knackered
