In reply to Tom Ripley:
That's interesting Tom - looking at the Ace and the Ballet side by side on the Boreal site, the Ballet looks rather like just a high top version of the Ace - a bit like Scarpa do their techy trad shoe, can't remember the name, as a 'lo' and a 'mid'. But it sounds like from your experience the Ballet is quite a different last? I think you said you have quite wide feet don't you?
I remember trying on Ace and Ninjas back in the 90s and they seemed SOOOOooo ridiculously narrow, that they were completely wrong for my wide feet. I've tried Jokers in a shop once too I think, and they were too narrow - so I've basically just had Boreal written off in my head as "not for me". The new Ballets look quite cool though in a retro/I'm into offwidths sort of way!
