Laces are decent, if they’re not slippery laces as you cna adjust tension across the foot and they kinda grip the eyes.
triple Velcro straps are ok as an alternative.
I’ve used some of the speed lace types, with the woggle/toggle whatever it’s called. found them to uneavenly tension the shoe, or at least not allow that much adjustment. I cound get the collar part tight, whilst not cutting off curculation to my toes, but over a ride it’d even out and my toes would end up with too much tension mid ride and any adjustment of the collar bit would just lead to more tension at my toes.
Havent tried the boa, but I’d think, for me it’s be the same as the speedlace, unless there are separate toe/mid/cuff areas.
