There was a climb in Eldo I could only lead in my Shoenards. C'est La Vie edging up that crux dihedral. Ironically they were only needed for one foot and one move, and on the next move (smearing) I wished I could magically change shoes.
I'm sure better climbers have done both moves barefoot.
these were from "san marco", italy. came out at the beginning of the 80'.
as i remember somehow patrick berhault was involved, wether seeing him climbing in this shoes and/or putting his name on it.
pretty comfortable but the rand didn't hold up well.
bought it in the lacedelli store in cortina.
