To maybe give an idea on how important those shoes that Alex wore were - or at least how perfect they were for the ascent: the athlete that designed them w/Sportiva, Tommy Caldwell put up all but two of the free routes on El Capitan (so only 8 or so in total), including the hardest free route on the wall. The shoes were effectively made for that one area.
Huber Brothers did more than 2 (Freerider, Golden Gate, El Nino, Zodiac). Skinner and Piana freed Salathe, Lynn freed the Nose. Most repeats aren't done in TC Pros.
