The TN Pro is the fully tested signature model by Tomoa Narasaki. Complete with a slingshot heel design for sensitive heel hooking, the outside of the heel is wrapped in RH rubber for exceptionally stable heel hooks. The 4.2 mm RH rubber sole allows for a longer life than other soft rubber shoes. Though the rubber is soft and sticky, the stiff midsole, along with the slingshot heel design, produces an aggressive downturn that can still stand on small footholds. Inside, the shoe annihilates. With a more rounded toe than most bouldering shoes, the TN Pro is most at home on steep overhangs requiring heel hooks and toe hooks. The rounded toe allows margin for error on dynamic foot movements that would be exceptionally useful in volume-based competitions or indoor climbing.
