This may of course just be a coincidence and bad luck but I had a horrible experience on my recent commute that I would like to share to highlight any concerns. I have only used them on a handful of occasions, a few runs to the supermarket and back or round the block up until last week when I finally got round to commuting to work. This is 16.5 miles each way, so maybe not the average commute but I shall continue... The pictures below show what happened on the return home journey. I was thinking the unclipping action at traffic lights was becoming awkward, maybe I was just losing the edge and becoming un-coordinated: As I approaced a busy crossroads about 1.5 miles from home I realised I could not unclip <panic>. Luckily I managed to creep to a set of railings and lean just in the nick of time. To my horror I realised both cleats/shoe plates had come away so it was nigh on impossible to clip out! After this event I got home and studied the shoes, one was still attached to the pedal which I would address later this weekend. It seems the construction of the shoe sole is extremely weak and allows when some force is applied to move unlosening the bolts. I have now ordered a proper pair of shimano branded MTB shoes to hopefully reinstate my faith in the technology. I hope nobody else has had such a similar incident on the cheap shoes, but if you have.. please share!
