David Lamblwrote a review of Black Diamond Neve Strap Crampons + ABS on December 15, 2016
Familiarity: I've used it once or twice and have initial impressions
The advantage of these crampons is weight - they are much lighter than my metal Grivel G12 crampons. However, my biggest issue is with the fit. I got these to use with my softer hiking boots. My size is US 13 and I couldn't get a tight fit in my heel even for moderately difficult terrain. I actually lost one of them passing through deep snow to Mt. Jefferson without realizing it.
My fully automatic Grivel crampons I use with my mountaineering boots and ski boots have much better fit. Of course they wouldn't go with softer hiking boots. I would recommend automatic crampons for all boots that fit them. If you need to pick the strap crampons, for smaller size boots the fit will be most likely better than with my size 13.
