I'm on my second pair of Sidis. I've had a pair of Genius for about 10-12 years or maybe even more. They have two velcro straps and a buckle. They're great shoes and I expect they'll last longer. Based on that I recently bought the latest version of the Dominator to replace some Bontrager RL's I've had for many very satisfactory years, certainly enough usage for me to be 100% satisfied with their function and value. But they haven't matched the uber-exceptional Genius shoes.

Anyway both the Genius and Bontragers had two velcro straps and a buckle at the top. (Diffrent buckles, but functionally the same). I've been happy with this arrangement. It seems I never mess with the velcro straps. They stay the way they are and I just unbuckle the top to slip them on and off.

I kind of like the Boa-type closure though. It does seem to make an all-around adjustment of the whole shoe easier. I've compared the Sidi version to an actual Boa and agree with other who think the actual Boa works better. However, after using the Sidis for a season now, I'll also say it's no big deal. I've figured out cues to get at the lever without too much hunting and have more or less mastered adjusting the tightness while riding without looking down. No big deal at this point, and since the Sidis fit well and wear very well - and I can order them mail order to overcome the dearth of options locally - I'll probably stick with the brand.
