Boots with wide/squarish toe?

So the universe saw fit to give me weird flippers (and didn't have the decency to make them webbed) that make boot fitting annoying due to not quite being shoe-shaped (basically a size 11 that got chopped off to be 10.5 length.)

I fully expect to fit and probably blow out any boot I get, but does anyone have a recommendation for a boot that relatively wide or square-ish toe box so I have less work to do?

Otherwise 28.5-29.5 Wide, slightly above average volume. 95+% piste. NTN or 75mm fine.

Spent the last 10-15 years in a pair of Garmont Gaaras that never did fit quite right and which are now, sadly, dying.

Marked NSFW for foot pics. First one is the original footbed of my Gaaras laid on my foot.
