And laced boots never need to be retightened? I own Ride Jackon Boas (my second pair) and I love'em. Like rocker vs camber, Flow vs traditional, this is one of those subjects that generate a lot of loud opinion without a lot of decisive factual backup. No offense to your friend, but she is probably just repeating something she heard someone else say.
I retighten my boas after my first run, and I may have to retighten them once or twice during the day, but that's just a matter of cranking the dials a few times. You'll spend more time fiddling with your goggles.
Coffee is your friend. Everyone else is an acquaintance.
