It's hard for children to focus in climbing school when their feet feel as scrunched as a ballerina's. Black Diamond's Momentum Climbing Shoe balances comfort with performance so they can learn how to climb comfortably. Most climbing shoes opt for leather or synthetic leather uppers to keep durable throughout their rocky adventures. Black Diamond, on the other hand, made this shoe's upper out of a unique knit that enhances breathability without hindering overall durability. This enhanced breathability also decreases the foul smells that standard leather climbing shoes excrete in your car, closet, or wherever you store their climbing shoes. The NeoFriction rubber sole is also unique in that it's molded-as opposed to the usual cutting from one sheet of rubber-to the shoe in order to increase longevity and ensure traction on greasy, plastic footholds.
