This new version of the Scarpa SL holds true to the heritage of this boot by having a good stiff sole with an aggressive lug pattern, so you can kick the edges into the snow or crunch through scree with stability and comfort. But now you also get a rubber rand for even more durability, while new eyelets (which have very effective rollers allowing precise and fast lacing) and styling give the boot a little extra appeal. Put this boot on and comfort is noticceably better than in the past, thanks to a little more flex in the ankle cuff, a new footbed with better cushioning and the addition of memory foam. The result is all that great performance on rock, scree and snow remains but there is now buckets of extra comfort. You don't get a waterproof lining, but the leather upper is very high quality and with a proper and vigilant aftercare regime (which you should be following anyway) this will guarantee dry feet.
The weight of the Scarpa SL Activ is reasonable to, at 2130g for a pair of size 46, when you take into account the performance.
In summary the Scarpa SL Activ does everything the Scarpa SL did before, but even better!
