I wear EU45 boots and was planning to order a pair of Grivel Rambo's when it came to my mind that they may not fit. With my G12's and Spantiks I am one hole off from using the regular bars, and thus had to get the extender bars. It's an 8 hour drive to anywhere I could try them myself, assuming they are even in stock. So, does anyone have any information/experience on this? Thanks.
