Er, no. I’m not seeing a balanced discussion here from the author, just the positives, of which there are indeed a good handful, of course. Whilst the shoe is still new…
To be blunt, they’re really a bit too delicate to work well in the real mountain biking world, the Boa system is prone to failures when heavily scuffed on rocks which causes damage to the coating on the wire. It becomes progressively harder to tighten, as the plastic coating gradually wears off and the wire is then reluctant to wind into the mechanism.
Grit and mud will eventually penetrate and gunge up the mechanism, exacerbating a sticky wire. The dial cap can be ripped off in an impact and I’ve had a wire snap. It can be repaired, sure but it’s fiddly and time consuming to get right; I’ve done it twice now to rescue damaged mechanisms and get value from the original shoe purchase but that’s enough for me.
Maybe it depends on where you ride; if its groomed trails, trail centres and dry locations perhaps.
After two pairs of shoes equipped with these, it’s a ‘never again’ from me. I’ll stick to simpler technology that’s much more reliable. Not all advances are worthwhile.
