i have mavics with their own version of boa.

i like it far more than buckles (fiddly). but they do get slightly loose over a ride. enough that i could ratchet it 1 click or 2 during the ride. (but i dont, because it doesnt really affect performance).

i like laces and velcros perfectly fine. only problem is when velcros are combined with laces... that the velcros tear up the thin silky laces if they come in contact.

which comes down to my last point, i think its really absurd when simply for the purpose of differentiation and introducing a new product, manufacturers will mix different closures on a single shoe...... utterly superfluous and absurd. oh and how they keep telling you how stiff the sole is even though its connected to that soft fleshy thing that is your foot, and that your legs transmit lots of pressure directly to the ball of the foot - not levered from the heel.

but anyway.
