Lake shoes, within a year one BOA adjuster broke - BOA sent the replacement, easy fix.
Within months of that, the other shoe's BOA broke - but this time it was the base that is sewn into the shoe. BOA says we don't warranty that part, Lake said out of warranty.
Was going to go back to ratchet or velcro (I just can't go back to laces, I'm too sloppy and invariably forget to do the right foot differently from the left foot) but Sidi shoes with their version of the BOA style closure plus velcro straps was on sale and I went for those. The way they work seems like they would be more failure-prone than BOA, but so far they are problem free.
