This feature is common to less structured shoes such as climbing slippers, whose softer sole allows the climber to “feel” the rock beneath his feet, while adapting to different types of hold. On a scale from one to fi ve, these register superior adaptability/sensitivity.

A feature common to more structured shoes. With their rigid sole, they are capable of supporting the climber’s weight but adapt less to the different rock types. On a scale of one to fi ve, the graph indicates superior rigidity/support.

On a scale from one to five, these are the growing widths for each model.

With this parameter we show how tightly the shoe needs to be worn in order to maintain its performance features. The grades range from 1 to 5: from shoes that must be worn smaller (grade 1) to those that can be worn more “comfortably” (grade 5) to maintain their performance level.
