Wondering if any BOA users have tried the K2 Contour? I had DCs with a single BOA. Upgraded to the Ride Cadence with Double BOA. Getting some heel lift w/that, but I think I was improperly sized (1/2 size too big, fit great for a while, but they've since stretched out giving me the heel lift). Was looking at the K2 Contour, but it looks like the Double BOA isn't a true Double Boa for Lower & Upper zones, but rather the 2nd BOA is for the liner. I've gotten used to being able to adjust my upper and lower and wondering if the Contour would give me a similar feel that the Ride Double BOA has or if I'll be missing that lower BOA for the boot.
