Screw the Petzl D-Lynx Crampon directly onto your shoes and experience lightweight rigidity like you never felt before with your old, bulky crampons. You can configure the interchangeable front mono-point into shorter or longer positions depending on whether you're dry tooling, ice climbing, or mixed climbing that day. You can also position the front and back of the crampon on your boot. Petzl designed the shape and angle of each point for expert use only.
