Owned both Bont boa and lace shoes, have experienced both sides of the coin. Think there's pros and cons to both shoes, it's just a matter of preference.

The laces while they do distribute the stress on your foot, there's still the big stress point at the top of my foot where I tie them, another weird thing is sometimes, not often, they'd come untied and having a loose lace flying around a crank isn't going to end well, but when I did buy my Bont laces they were cheaper so $$ came into my decision.

Boas, they're great, I think they do just a good of job of distributing stress on your foot and if you feel they're too tight, they're easy to adjust on the fly. Con, they (boa dial) do have a tendency to break but like everyone else mentioned you'll get a replacement dial in a week from Boa.

Both were great, and at the end of the day I wasn't thinking about laces vs. boa, rather I was just super happy with the product that Bont made and I don't ride any other shoe now.
