Yeah, I'm surprised it lasted as long as it did, too. Seemed way to niche for most of the year to really pull in the sales needed for a location like that. I'm sure during the various run weekends business was gangbusters and I know as sure as I type this, a dozen people will come out taking about how they're runners and loved this store but relative to the number of people in Disney Springs at any given moment, I'd have to imagine their potential customer base was only ever a tiny, tiny fraction.
Would have made a lot more sense as a popup during event weekends but I imagine that Disney wouldn't have wanted to partner just for that and they were probably expecting enough business from these things and the common vacationer with bad feet from walking to make up the rest of the year.
I think if we were going to see more Disney-specific stuff in a shop like that though, it would have probably been Disney managed.
