the only thing that could be different is the liner. the shells are EXACTLY the same. and if you say the flex is the same. im 99% sure the model a liner is a heat modelable liner so you cant lose with those. check out www.evogear.com . they were on there for like $160 with the discount theyre running now. hella cheap me thinks
they are both soft as SHIT, but there is a BIG difference in these boots, the booter has an intuition linr in it and the a-model doesnt. and unless you dont care about the intuition liner then get the booter's
Read your boot post from before on the question about the best boot. Intuition liners wrap your leg better certain intuition models have no tounge. Soft boots won't help you reduce "shin bang" unless you are going from a boot that is to stiff for your body shape.
