So last year, New Balance got ambitious and announced that they were going to put out new shoe designs for each race weekend. I think they sort of lost steam by the time the
Disneyland Half weekend rolled around (that's the last time I remember them putting out a new design in 2015, the Donald ones). They didn't make any such announcement this year, which is why I'm assuming that there are no new designs and that they're just sticking with what has been available so far.
At some of the earlier race weekends I think they had some of the shoes left over from 2015 that they were trying to unload, but other than that, I'd expect to just see Ariels, Dumbos and M&Ms.
They will, I think they were posting the SWDS schedule to Facebook. Is it not in the Event Guide (which I still mostly cannot open)?
