When I bought my Gaerne boots, I called them directly to find a dealer. They told me that there are very few dealers that stock them, especially the Explorer and especially in these economic conditions.
He did say however that just about any mc accessories dealer can special-order them and that they fit very true to street-shoe sizing.
I ended up buying them from motorcycle superstore.
