I have some Murrays and I love them. I will also say that I have very weird feet, very, very flat, and no arch. I have to wear custom inserts in everyday shoes, and my snowboard and snowski boots. So for me to just find boots that feel good for my feet is a challenge, and I normally go through bindings every other year as the support starts to fade from the boot. So the actual comfort in the boot is going to very different for a normal person.
This is the best fitting boot I have ever had, and I have worn my boots around marinas, waterfront restaurants, and other random places that footware would be a smart idea, because they are more comfortable than my sandals. The edging is awesome, I feel like my feet are bolted to the board. I feel like I am complete control of every inch of the board both on the water and in the air. The big air landings are nice too, not the softest boot I have had, but firm and very comfortable. One of the easier boots for big air I have ever had. I love them, and while the initial investment was more than I had hoped for, I am hoping that when I break something or something wears out I only have to buy a part of the system and not the whole set, so my next boot purchase will be about $50 to a $100 less than a typical boot, which for me will add up over a 4 year time period.
My biggest suggestion after owning over 10 pairs of bindings through the years, buy the binding that will fit your style. By that if you are big on tweaked grabs, then find some flexable boots. If you go big find soft foot pad boots. They are like a good pair of running shoes, you are going to beat the hell out of them, find something that feels best on your foot, they may be the most expensive or they may be the cheapest, dont let either keep you from buying them. All the major brands have a different feel overall, so try as many as you can on, then jump in place or try grabbing around like you are on a board, that will give you an idea of what the boot will feel like.
