A material based on a technique, called kirigami (a relative of the folding technique, origami) of cutting a flexible three dimensional pattern into a surface has demonstrated increased friction between a slippery surface, such as, but not necessarily confined to, ice, and the sole of a shoe. In the case of the shoe-sole, the pattern is cut into a thin sheet of steel. The increase in friction is estimated as 20% to 35%, at the current state of development. The information I have seen concentrates on reducing falls among the elderly, and says nothing about its potential use in sports, such as climbing.
Assuming a comfortable, light weight, and durable climbing shoe can be made with a kirigami sole, is this innovation (not yet on the market) substantial enough to be likely to change climbing grades and/or the rules for climbing competition? Please base your answers on the results of other effective innovations in sports gear on the rules and practices of the sports to which they are applicable.
The flexible kirigami sole mimics the motion of a snake's skin as she slithers, or the action of a cheetah's semi-retractable claws in a high speed chase.
