This shoe is very comfortable.  I replaced my old MT572 trail running shoes with these when my feet started hurting from them getting too worn.  The 610 provides good stability and decent cushioning, and I can wear them for many hours (at work and home) without discomfort.  I don't run in these - they're really just for casual standing/walking.

My only complaints are 1) sometimes one of the tongues moves over to the side of my instep, and 2) they have started squeaking when I walk.  Issue #1 is less pronounced than it was with my 572s, but it still happens occasionally and is somewhat annoying.  Issue #2 happens with every step, every day.  I can no longer sidle up to unsuspecting coworkers.  I believe the squeaking is coming from where the laces are rubbing against the instep toward the toebox, but it's hard to tell.

Both complaints are fairly minor, and I still like these shoes a lot.
