the boots are solid. my first boa boots, and it works good. it is true that lower half of the boots doesnt get as tight as the upper with boa, but it didnt bother me at all when riding. these are my 3rd dc's and as ususal, they fit about one full size smaller. im not sure if im a fan of air pumps,,,,but its just a matter of personal likings. i mainly ride backcountry, trees, chutes, cliffs,,,,pretty much anything natural with little tiny bit of park when the weather is crap and they are have the perfect flex for what i like to do.
