Familiarity: I've used it several times
Fit: True to size
I already have Gandas, and Ganda Guides. I wanted something for hot conditions, mesh/ breathable but still with nice climbing rubber sole. I love the way the full lace system in La Sportiva Gandas work, nice snug fit tht is highly adjustable. The Xplorer's lace system is very similar, and provides a very adjustable fit. They are as light a anything out there, and very comfy right out of box if you like the way typical La Sportiva fits. The sole is more of a hybrid...more aggressive hiking pattern with a climbing toe forward. Its not the dots like the Ganda, so is likely not quite as good a climber, but should be a better all around approach shoe. I wear 44 Gandas, and the 43 1/2 Xplorer fits with just a touch more room. I think 1/2 size down is about right.
I think this will be a great shoe for hot and humid, as well as desert approaches, and is still nice and light for hanging off your harness for the hike off. Its a nice looking shoe on your feet too. Definitely worth a look at under $120!
