i was in hill sound today buying their trail crampons and asked the designer and owner the exact same question …
i was hoping that the trail pro crampons could be used for both my mountain boots and trail runners

he expressely noted that they wouldnt and that bars if flexed enough would retain the warp, they dont spring back to their original shape over time
he indicated the Katooha KTS, noting that they had a patent on the multilayer leaf spring they use
now i know this doesnt answer the question about the BD contacts … but i suspect they would have a similar issue, ive heard that there might be more flexible bars you can get, but does it warp over time …
anyways it removes one set of crampons from the mix … the hillsound guys were very honest, saying that theirs would not be recommended outright … which is too bad cause it only costs $80 and weight like 680g
i got a set of the trail crampons instead
