I just tried them on my Asolo GTX hiking boots. All i did was walk around my office for a few minutes so its hard to say but they seemed solid. Guess ill have to wait for the winter to say for sure but so far so good.

these are not ideal for hiking boots, because of the rear bail. that is meant to snap into the groove on mountaineering style boots.
you want a pair of crampons that has a strap on the back, just like the strap on the front of this pair, rather than the wire bail. those are a lot more versatile for general use, because you can even put them on with sneakers, in a pinch. it is possible to force these to work on normal hiking boots, but it is definitely not ideal. grivel makes a really nice crampon, with webbing straps for front and back, which are lighter and more packable. the stiff plastic on these makes it a little less convenient to stow them away in a compact fashion.

They will work with those boots, BUT those boots will not serve you well for extended time on snow and ice. No stiff shank and insulation will equal cold and tired feet.

Definitely not the cyborg. Vertical front points vs. horizontal front points will not serve you well on neve and other firm snow conditions. You want these things to get purchase in the softer mediums. For the harder mediums of ice, and the steep and technical the sabretooths actually climb really, really well. Its only on chandeliered ice and mixed climbing that you will notice a big difference of performance. Don't let Angus steer you wrong here!

I would go with the sabertooths. Sounds like you will be spending more time mountaineering vs. ice climbing. The cyborbs rock on vertical ice, where the sabertooths only perform average to well. The sabertooths will really excel on glacial travel, moderate ice route WI 4 and the will be great on alpine ice which you will see lots of on both mountains. I climbed the north side of Rainier years ago with an older set of sabertooths (old step-in style) and I would pick them again in a heart beat for all my mountaineering. Plus, with the Sabertooths you can use them on a boot that does not a toe lug, so you gain a little versitility there. Good luck on your climbs.

The Cyborg. I explain further on that page.

If your feet are too big, you can buy longer center bars. I wear size 14s and had to buy the long center bars. It would be nice if they allowed to you to purchase crampons with the longer center bars rather than having to buy the shorter "regular" crampons and purchase the long center bars separately.

Nope, there aren't. See that orange tongue of metal in the center of the crampon with the holes in it? That adjusts to fit any shoe size.

Should work no problem, but you can get a full front bail crampon to work on those boots as well.

You want to get something like this:

There are serveral different options. You can see them under this product group:

you will want a pair of automatic crampons for those boots but any crampon binding system will work on those boots. if you have large feet you will need extension bars

Yes they will, it is the neumatic attachment, a great crampon for that boot, but be weary of trying to climb harder ice in those boots, as the 3/4 shank will flex alot!

Not really, the Tele bill is too big. For telemark compatibility check out the Black Diamond Neve Pro Crampons:http://www.backcountry.com/store/BLD1049/Black-Diamond-Neve-Pro-Crampons-with-ABS.html

Yes.

yes, as long as they have that ledge on the back...don't be scared of strap on crampons if you are just doing general glacier walking

So you reckon it would also fit on a telemark boot (27)? The front strap should fit well, or it would need the version with the wire/bar in front?
