Climbing shoe sizing varies from brand to brand and, just to confuse the issue, often from model to model within a brand. Use numerical sizes purely as a guideline. As a rule of thumb, the level of shoe discomfort increases proportionately to an increase in climbing "level". This is primarily a result of molding the foot into as firm and precise an appendage as possible in an effort to eliminate "roll" (due mainly to weak feet or the shoe being to big and rolling around your foot) and increase sensitivity (sensual feedback) and pin-point controlled.
