great friction, bad glue
picked up a pair last May.... i climb 3-5 days a week through summer, 4 months later the adhesive bonding the rubber to the leather is failing, and the rubber over the toe blew out. the soles look great still! i'm thinking i got a bad pair, as i know many avid climbers that rock these season after season. the fit was great for my flat foot, took a few day to break in as any leather shoe does. buy 'em somewhere you can return 'em if you have the adhesive issue i did.
