The Grivel Spider Instep Crampon is a ten-pointed polyamide structure, which does not require adjustment, and adapts to any type of shoe, in any size.
Properly used, the Spider will provide an important margin of safety to the trekker who finds himself on snow, iced-over trails, wet grass and heather or simply hiking on steep, muddy terrain. Their light weight and small pack size make them particularly helpful to hillwalkers and mountain photographers, who might find themselves on icy ground, and the Spiders are especially useful to professionals who encounter snow and ice on a daily basis in winter such as park rangers or equipment operators at ski resorts.
Mountain Rescue Teams will appreciate the fact that Spiders may be adjusted to any shoes without tools. The two parts fit together with the points facing inwards for easy and safe transportation.
