Kahtoola KTS Crampons

The KTS crampons are designed to fit most flexible hiking boots. Because they use an independent binding system, they are more versatile than rigid mountaineering crampons, but they are not intended for use with soft-soled trail runners or boots without a defined heel welt.

The integrated skins act as a barrier between the crampon frame and the snow. By preventing snow from sticking and packing into the underside of the crampon, they stop 'balling'—that dangerous buildup of ice that can make your footing slippery.

Yes, the binding system is tool-free. You can easily tighten or loosen the straps to customize the fit to your specific boot while wearing gloves, which is helpful if your boots expand or contract with temperature changes.

The KTS crampons weigh between 656g and 684g depending on the size. While they aren't ultralight, the folding heel bail allows them to pack down to a compact 20cm x 9cm x 9cm, making them easy to stow inside your pack when you hit dry ground.

Unlike rigid crampons that force your foot into a flat, unnatural stride, the Leafspring Flexbar allows the crampon to flex with your boot's sole. This creates a more natural walking gait, which reduces fatigue during long treks on uneven terrain.

The 1-inch chromoly steel spikes are durable, but they will eventually dull with heavy use on rock or mixed terrain. You can touch them up with a standard metal file, but avoid using power tools, as excessive heat can compromise the steel's temper.
