Wore the FSBs out , really quick to grab dinner. We don't have snow here in California so I can't comment on that but they worked well in the rain. Overall the shoe is a bit heavier and doesn't have that lunar cushion but they are comfortable. The sole is like a comfortable boot. The 3m panels really stiffin the front so didn't see the typical bit shoe flyknit curving. The boot itself is a little bit bigger, almost like the htm model (it's more straight on the heel vs a curve). The tounge also has that matching flyknit touch. On the inside, the entire shoe has that wool and water replant lining. My feet felt warm (they generally feel cold during winter nights in normal flyknit. I wear my hyperfeels to the gym every night and definitely can feel the cold in those).
