I like the intention, but until there is an opportunity to try it, I am not sure how grippy this can get with the pins there were suppose to fit between the thread of the shoe bottom, now fully enlarged.
Why not get the cheap plastic pedals with the plastic pins that are already molded into it?
I am all for inventing something that can save the shins, but just like many other options before this, it tried to solve the problem, but took the original traction benefits of the pins out of the picture.
Someone once suggested putting the pins on the shoe bottom, then have the 5Ten rubber on the pedal. Love to explore that instead.
With all these said, they are all talks in theory without actually trying the product. Pink bike please test them out.
