The fit of the Overload will definitely be more conducive to alleviating 6th toe pressure because of the Live Fit zone which is directly over the "problem spot" on the outside of the foot. It will expand as necessary or not depending on what your foot needs while at the same time not detracting from the performance of the boot at all. The heel of the last is super narrow and the moldale foam we use in the liner is quite firm, so that combination will equate to a solid heel fit for sure.
In general, foot hold comes from last shape, liner construction, and being in the right size more so than the number of buckles on a boot. Buckles obviously contribute to fit, but you'll find that this boot will either fit nor not because of the last shape more than anything. But we made the buckles as large and as supportive as possible because they do serve an obvious purpose. And by reducing the buckle count to 2 we minimize any excess weight. The Overload 120 weighs in at barely over 2000 grams per half pair, which makes it one of the lightest boots in this category.
Once you guys can try it on you'll see just how secure your foot is inside the boot and like Gus and the rest of our team are demonstrating, the boot performs to their super high expectations.
