I've had these shoes for about a month and wear them everyday - almost all day. They're good - not great - but good. I have my own insert, so I can't comment on how the fit would work with the NB insert, but otherwise the fit is true to size.

It's not a hiking or running shoe - but then it doesn't claim to be. It's fine on a rocky trail(one level tougher than hiking in running shoes), although you feel the rocks through the sole and it doesn't give the support you'd look for in a light hiker. The cushion is firm throughout the footbed, but not spongy like a running shoe - my knees have no complaints. It does not have the rocker feel you get with some light hikers where you want to keep walking.

I would recommend it for someone who wants a waterproof shoe for easy walking in the neighborhood, on paved trails or trips to the dog park.
