In reply to Dheorl:
I got a pair of Trango Ice Cubes in the late Autumn of 2015. The sizing is exactly the same as Nepal Extremes and the Batura IMO. They are extremely light and very stiff, I was also sceptical about whether they would be warm enough for real winter cold. I used them in January 2016 at the Sottoguda ice festival in the Dolomites and was shocked at how warm and comfortable they were for all day use in temperatures between -8 and -14 degrees C. I generally don't suffer from cold feet, and I forgot that I was wearing these. I then used them on Scottish mixed in Glen Coe and on the Ben, then managed to get on Mega Route X later in the season. They were warm and precise, and they really looked after me.
For proper Alpine winter I would probably still wear the Batura (very warm) but for everything else (Scotland and euro ice cragging) I would use the Trango ice cube. Too early to comment on durability but at this weight I don't expect them to last forever. I used them with Grivel Rambo 4s and Grivel G20s, the fit was better on the G20s.
The gaiter will fold down or you could leave it unzipped for the walk in. If I was going over the top of Mont Blanc or upto 5000m in the Spring or Autumn I would use the ice cubes - I don't suffer from cold feet, so you'll have to make your own call on that one. I've not used the Nepal cubes so can't give you a fair comparison. Good luck with your adventures............Jeff
