Compacted snow is mostly ridable on any studded tyre, but if it's relatively fresh you can get to the point where the tyre grips well enough, but the layers of snow shear and take your wheel with it.  This is more like sliding on mud than on sheet ice, so if you're used to off-road riding you're relatively unlikely to end up on your arse.

Not had that as an issue yet. How deep does the snow need to be for this to happen?

I found it was a problem last December when I went out to play (with the Ice Spikers that had been gathering dust for a year and a half since I bought them) in the ~100mm of snow that came down overnight.  I'd dropped the pressure right down to the sweet spot (maybe 12-15PSI) for the virgin snow in the nearby park, and when returning home by road discovered that riding *in* the freshly-formed vehicle ruts was a bit exciting for this reason.  I suspect that higher tyre pressure would have solved the problem - which I didn't experience on the way out - but I wasn't going to muck about inflating tyres when all of 1.5km from home.

I've experienced something similar with a Marathon Winter on the rear wheel of the trike on partially re-frozen foot-trodden snow, but it's just a momentary traction issue when you have an extra wheel.

I've ridden a few miles on Marathon Winters and don't believe that they have the Marathon anti-puncture layer. I believe that the 'winter' tyres are built on the marathon XR tyres. They actually puncture quite easily, in my experience.

I don't think I've actually had a visitation on one, but they're certainly not up to the levels of puncture protection that you ideally want if your fingers are going to freeze in the time it takes to change a tyre.  Hence the new Marathon Winter Plus model, presumably.

Winters arrived. They work perfectly. Ice has vanished, even before they were fitted on the bike.

Actually, I lie. There is still black ice in the mornings on the fen roads. I'm still going to use the studded tyres for a while, simply because I can't afford another knock on my noggin. Can use the short route to work (bike to local station, 2.5miles) for a while, then I'll try the riverside cyclepath. That wasn't great on previous tyres, they weren't so good on grip, but the winters are a bit more suitable.
