When walking with a lot of ice, always walk on the snowy, cloudy, and/or crunchy looking areas. You'll get more grip with the crunch of the ice and snow than on just ice. If it looks clear, didn't go near. (Or something like that)
Not sure about reliability and BFL, but Hoka has X-wide sizes. I tried to find what that meant in the standard scale. However, their toe boxes tend to be pretty wide already.
Edit: found on a separate website their X-wide is 4E.
Honestly, they're not even that bad. Besides being kegsbreath.
