If you need some more traction on your walks over technical terrain, the Mini Crampon 6 P from Climbing Technology could be of service.
The six hardened steel teeth really make a huge difference. These spikes may have little in common with crampons (with the exception of the teeth), but they are quite versatile and can be used in winter or for hunting and forestry work.
They will fit on any shoe and are easy to attach with the straps. Small and compact, the Mini Crampon 6 P will fit in just about any bag!
