Nothing, did not get much interest in the vibram soled version and I don't like the wedge soled version. If Haraki decides to do another run, I may get some made, but I am not going to initiate a run just for me I am afraid.
As per your comment, the limiting factor is the instep….stretching it out is a task. Currently need plastic bags to get the right foot on. Left is good.
Hopefully what Morgan's suggested solution of stretching them in advance might help future owners. Unless you
might want to try natehate advice of using a wiski bottle.
