These angular-shaped footholds suit novice and intermediate climbers on vertical to low-angled walls. They require climbers to use commercial climbing shoes to stand on with their toes and offer neutral to sloping areas. Their size makes them more challenging, but they are still in the easier range on lower-angled walls. We love this set as footholds for our intermediate to advanced power endurance circuits on our 25-degree wall.
In steep terrain, engaging your core will help you press into the holds. It's worth noting that you won't be able to cheat by dragging your toes, as there are no incuts to offer that kind of purchase.
