Substainal and look extremely durable. Sadly I didn't get to use them on my trip due to altitude sickness. They'd been purchased for traversing across a Glacier at 22,000ft, but should be great even in the mountains in a British winter. Can't wait to try them properly

I am impressed with quality of the product.Size is adjusted easily (and reliably), sturdy. Locks solidly over hiking boots (the model that I got is not intended for any technical ice-climbing)Fairly simple to put on (if you are not familiar with crampons - put them on at home, it is not fun trying to figure it out when it is cold and dark).

Works great, just make sure you don’t have big rounded toe and heel co structure in your boot.A few of us did some alpine hiking in Colorado in June (snow) and needed these. Two of us had boots with rounded toe and heel rubber. Great for hiking but they don’t match well with these. They kept falling off. We ended up tightening them so hard that my toes of the boot bent up significantly and my foot arched backward. Only then did they stay on.Great product just get some boots that will work well with crampons if you’re really going to depend on them.
