Josh A.wrote a review of La Sportiva Mantis Climbing Shoe on August 30, 2008
As a small sz 12 street shoe, I ordered a size 45.5 in these. Out of the box the fit was a bit tight, which equated to significant pain on the first few climbs. after baking them in the sun on some warm climbs (~10 pitches) they fit like a glove and climb hard. The fat rand is priceless for the inevitable Teton crack jams here n there.
