Based on my research, this is the only pair of 27.5 Fischer RC4 MV Pro BOA ZF boots for sale in North America.  These boots are for expert skiers that are looking for a precision fit for the ultimate energy transfer from foot to ski.  Please note that these boots come with a stock Zipfit liner ($500 value) that will last 1000+ ski days and provides the ultimate heel hold along with ultimate comfort.  Note:  boots do not have factory insoles.  These insoles should be thrown away anyways and replaced with custom or performance insoles.  Note:  boots will be shipped in a Fischer boot box but not the original box.
