This is technically the same shoe as the Dominator 5, the only difference being that the Mega version is made in a wider fitting to accomadate a wider range of wearers.

Unlike some of their competitors Sidi have taken note of the fact that different people have different feet. It's common for a particular manufacturer to be known for a certain fitting style, with the Italian makers tending to suit a narrow foot and certain others renowned for their wider fitting.
Sidi have at least made an effort to cater for a broader range of customer by producing many of their models in a Mega fitting, which should be comfortable if your feet feel a bit too squashed in the standard Sidi range.
