Those boots are expensive as hell. Driver Xs are stiff as hell.
Look into K2 T1s and TI DBs (DB has external BOA). Much cheaper, J-bars for heel hold, and they would appear to match your foot profile (wide forefoot, narrow heel).
Vans Contras (super stiff BOA), Wiigs, and Fargos (BOA) are some other choices, as well as the Cirros (dual BOA).
If you end up with the K2 T1s, you might want to finish off the Harshmellow setup with some K2 Auto Ever bindings. CO2s wouldn't be a bad freeride choice.
Although at your weight, super stiff is really going to be super stiff.
