Shoe only has front and outside edges (inside edge rounds up into the rand); outsole does not wrap up over the heelcup, which is rounder than on the regular Hiangle to prevent a built-up heel pushing you away from the climbing surface on morpho (3D) hooks.
The Hiangle Pro marries the marked downturn and precision toe of the regular Hiangle (reviewed in our 2020 gear guide issue, where it received our 2020 Editors’ Choice award)—a laser-cut edge on the outside and front of the sole—with an innovative inside/medial “edge” that is, in fact, not an edge at all. Instead, the outsole wraps up over the shoe in a continuous rand that thins from 3.5mm underfoot to 2.1mm over the toebox, giving you underfoot stability but plenty of flex on top of your foot for smearing/bent-ankle volume climbing. I.e., the design lets you edge on your big toe in the standard fashion, but then deform the shoe’s inside edge to stand on volumes and get more rubber-to-hold contact when you need to get your smear on. Also, the heel has been pared down (no outsole wrap) and rounded, so you can rock over volumes on the heel’s outside edge without having it push you away from the hold surface or wall.
