I never thought I would be so in love with a pair of shoes. But these are far and away the most comfortable shoes I've ever had. I've had them for 6 months now and I they're just as good (and comfy) as the day I bought them. I actually plan to buy several pairs, because I'm paranoid they'll stop making them, and I don't think I can do without them now!
I have a hard foot shape to fit properly generally (wide) and I also find most other shoes to be tight or heavy. Even when this isn't the case, and I've got a pair of shoes that are generally comfortable, they will usually start hurting if I use them a lot (go running, or hike all day or whatever). With these - nothing.
I like to go barefoot a lot, and usually take my shoes off as soon as I'm inside because I feel like my shoes constrict my feet, but not with these - it genuinely feels like I've just got socks on a lot of the time.
Also, they're billed as running shoes, but I'm not really reviewing them as such - I just use them as everyday all-the-time shoes.
The one downside to these shoes - and it is a big one depending where you live - is these are the *least* waterproof shoes I've ever seen. Completely impractical to wear if it's raining or snowing, and even if it's just drizzling, you might find they get soggy.
