My info: 6'4", 200 lbs. 10 years riding.
Got in an 11.5 this year. Tight at first, but these babies pack out a bit!
When I checked these out I was stoked on the inner BOA system that locks your heel down - it's as awesome as previous reviewers make it sound! Add that to the fact that I was able to size down an entire size from my boots last year and finally get off of those wide boards and I was sold.
Now, I'm a 100 day rider, and here's where I've ran into trouble. It's been 4 months on these bad boys, and although they were treating me awesome, they've started to totally fall apart.
The heel on my right foot has completely worn through, and snow slowly packs in throughout the day either creating an ice chunk that adds a horrid pressure point, or on those warmer days my foot is completely soaked.
The stitching on my left boot ripped out above the top of my foot, so now the BOA system tightens all wacky.
Not to mention seam-ripping on both feet, so it's hard for my feet to stay dry (although they do keep warm.)
TLDR; Heel-hold is amazing! Sadly, these boots don't last if you're a 100-day rider.
