Austin wrote a review of Scarpa Marathon Rock Climbing Shoe on December 18, 2009
These shoes are perfect for long routes with mixed terrain between pitches. Though I dont think they would be great for "grueling walk offs" as it says above, they are wonderful for scrambling from pitch to pitch and those places in between.
The shape of the shoe makes them much more comfortable than a more agressive climbing shoe. And though you trade off some precision, with a more relaxed toe shape and flatter sole profile, you get much more comfort.
Even with these comforting features the she still performs very well on cracks and moderate slab climbing. And its great not to have to take them off to move between pitches, or while slaving at the belay.
I got mine a little big so I could use them while wearing lightweight socks for colder assents in the sierra and north cascades. I have been very pleased with their performance.
