Very good review. I have these boots with after market insoles as well. My feet are really flat...I wear custom insoles in almost all of my shoes..the one exception is hiking boots.
I bought boots and insoles after my old boots destroyed my feet after just one day of riding at telluride. The lacing system took some getting use two...I would say three outings. Once I got use to it I rarely have to adjust after puting boot on. I do not like how the ends of the laces are stowed. I think the only reason they stay in place is because snow board pants ankle gaitor, I think that is what the tight elastic at the foot of snowboard pants is called. The boots fit really well. The toe box and heal box provide great support. The boots are tough to get off, but so where my other boots. I can ride in these all day without any kind of foot pain. I have been very happy with the boots.
