I purchased these crampons for an alpine touring trip in Switzerland. I needed to use them several times, and they always performed. They have some real advantages for this kind of trip. First, they are extremely light. In addition, the binding system is slick and makes for a very good fit on the boot (Lowa Structura) without straps going every which way. I recommend them highly.

These crampons should be in any self respecting ski mountaineers pack - super light but also strong. 390 grams! I've bent many other lightweight aluminum set-ups but not these. I worked them on hard quartzite and ice and they came out no worse for the wear. Excellent product - they also work fine with Tele boots contrary to other published reviews.

These crampons are very light and work well (have only used them once, and only on snow). They fit my size 12 Scarpa T-2 tele boots fine. In order to fit them on my size 12 T-1 boots, I had to notch the heels of my boots on each side, and I had to replace the ankle strap on the crampons with a longer strap. They attach securely.
