The front points are backed up by a set of secondary points immediately underneath, as well as a set behind and to the side. These points do surprisingly little to support the climber's foot, because they don't angle forward enough, and the ones on the side are set too far back to provide any torsional support. They work, barely. Snow plate limits the front points' penetration. Secondary points don't really support a climber's weight, and give minimal torsional stability.
Straight frame makes for awkward foot positioning.
A rigid, curved crampon that is fairly secure on steep ice. The front and secondary points aim in toward the big toe for a natural climbing stance, and the front points can be centered or offset under the big toe. Curved design allows for more natural foot positions, and offset mono point puts the power under the big toe. Splayed secondary points give extra stability. Front-point purchase is less secure than we'd like.
