I have a pair of micro spikes (second link) and use them fairly regularly in when hiking in the mountains in winter. They’re very good at what they’re designed for, hiking up trails on hardpack and ice and realistically unless you’re going mountaineering then you don’t really need a full set of crampons. If you’re likely to start needing to kick in or going off path then they’re probably not the equipment needed...
I’ll get flamed but realistically you’re likely to be fine with them. As seen in the Everest Base camp thread people tend to err on the extreme “safe”/overkill side of advice on this forum!
That said only you know your limits and experience...
As a brief follow up, we used the micro spikes throughout the trip and they worked fine. We took some pliers with us to reattached chains and links whenever they came loose, but they did the trick perfectly. That said, we stuck to largely good paths but did divert or turn back on a couple of occasions due to the weather. The first day walking up Pike O'Blisco was a lot of fun, 1m deep snow coming back off the other side of it. Around -7C on the peak meant lunch was a rapid and painful affair. One of our group had sprained an ankle 6 weeks before, so we abandoned our trip across Crinkle Crags to Bowfell after Blisco, as the clouds drew in and the pub beckoned.
The next day was the most severe, walking up the Band towards Bowfell. The locals in the pub that night said the local mountain report indicated were we in 100mph winds and a windchill of -30C... but I reckon it was more like 80mph and -20C. Either way, we got halfway up before knocking it on the head. The wind was such that even if we'd got round to the top of Bowfell, wouldn't have been able to see much. On our fourth day we did Stickle Ghyll, Harrison Stickle, Loft Crag and Pike O'Stickle, everything covered in snow but the sun was out. I've done that walk many times before, but those conditions were by far my favourite. A fair amount of hard crust on the snow was easily doable in the micro spikes. Ice axe wasn't needed on any days, but I used poles for the first time due to knee injuries, and they were a fantastic support.
Looks like we'll be back in Langdale for Christmas.
