Hit and miss with the Chuck IIs. I've worn a few pairs of these for a bunch of walking while traveling (10+ miles/day).

Things I like:
1) The Lunarlon insoles make these sooooo much more comfortable than the old Chucks, especially for walking around.
2) Though some folks aren't a huge fan of the styling (missing the racing stripe and all), it has grown on me. I like the burgundy shoes with burgundy laces, black shoes with black laces.
3) They fit like regular shoes should fit. Order your regular size, or a half size larger than what you wear with original Chucks.

Things I don't like:
1) Longevity leaves some to be desired. The middle part of the sole on two pairs has come apart from the edge on two different pairs. The rubber seems to wear faster than the older Chucks.
2) Some problems initially wearing them with the Lunarlon insole. The fabric that is glued on to the insole sometimes comes loose and starts peeling off. This is quite uncomfortable to have rubbing around on your heel.
