I've been wearing the Under Armour HAW 800 gram boots the past several years.... Wouldn't trade em for any boot I've had in the past.... I used to be a Lacrosse fan but the last pair of Alpha Burly's I had wore a hole around the ankle from normal wear within a year....
Have not tried on the Under Armour boots, but did pick up a pair, and run my hand down in them, and they felt really rough around the ankles, kind of like they may rub your ankles raw. No issues for you?
