Well, the pedal/shoe combo worked very well on my resurrected Frankentrail bike - monstrous levels of traction from the Five Ten shoes to the flat pedal pins, akin to being clipped in, despite it being “a little bit muddy”…

Had a few “moments” when I tried to twist my ankle to “unclip” (20 years of muscle memory at work…) only to find the pins held my shoe like it was locked tight - had to relearn lifting my foot up to get them off the pedals. 
NB didn’t raise or lower the seat at all - seemed fine as it was.
