You can call me a liar when you show me proof of any pro riding guys in single boa and really even double boa boots. No offense, and yes it's a tad of a blanket statement to say "every", but I have worked in the industry my entire life, ridden with pros from Lib and Flow and so on, spoken with just about every name you can imagine in the industry (yes it's true Danny Kass is a douchebag and Joseph Condorelli who runs Grenade now is even more of a coke head than you'll ever know), but every one of them rides/supports lace. Obviously you can tighten Boa boot's over and over until your foot falls off but that far from makes them the best fitting boot. I personally ride a Boa only because I was lucky to eventually find one that fit perfectly and don't have to have a budget for finding equipment. But People need to know the negatives and how these work. T-rice, White, Lago, Jones etc. don't ride Boa and they as well as I can put a lace boot on you so tight you'll lose feeling in your foot in minutes.
