Equiptment fitting is very subjective, as everyone has slightly different requirements. I'm 5'6" 135lbs., with decent size calves, skinny ankles, wide tow box. These boots fit me like a glove, and were not overly bulky or heavy. I'm a huge fan of the Tech 8's for thier protection when Moto-X, but don't like the weight/bulk in my size (8). When playing all day, I would reach for the Tech 7's. I consider both of these boots very good, just the SG1's fit like they were tailored, and build quality is super.
