They were tough to find but after looking around on the interwebs I found a skateshop in Colorado that had these shoes in two sizes. One was size 13 and the other was 8.5 (which just so happens to be my size).
If you aren’t familiar with the Barrier Kult (BA KU) then check out the video below. Basically it’s a rad group of skaters who want to preserve the integrity and purity of skateboarding. They aren’t in it for fame or recognition (hence the balaclavas). They are a part of the Barrier Kult so they can promote the ritualistic knifing of abrupt barrier transitions. And they do it well.
