In reply to simoninger:
One of the things that the Ace is particularly good at is cracks, and this is a crack - albeit a very steep/overhanging one! I would also argue (and I'm sure Andi would too) that the feet are indeed relevant, not least because I wouldn't fancy my chances at campussing through it...
When it comes to why the Ace are particularly good at this sort of thing, it all comes down to their supportive, full-length midsole, which means that rather than fold in two like a softer shoe might, it actually gives something back.
Also, I suspect they included it because it's a bit of a laugh. Just fun to see these things getting done, horrific though they might be!
