JT, you would go with a size 29 liner. Volume is trickier to say. You say you have hot spots but don't say if you have too much room or too snug in spots. If you have a narrow foot or looking to take up space, go with the MV. Need more room, LV.
Hello Ray, We do not have replacement BOA's for the Fischer boots. Your best bet is to contact Fischer warranty. The warranty period is 2 years, so include your purchase receipt and picture and hopefully they will ship you a new BOA at no cost.
