The smallfoot snowshoes come in 3 versions, a basic one for level walking, an advanced alpine version "Revolution II" for steep terrain with front and rear crampons, and the "Alpine" version with no crampons, designed for climbers who carry their crampons anyway, which can be used with any 10 point crampons. I bought the 2017/18 version of the "Alpine" model but with the front and rear crampons from the Revolution II as well (a long and complicated story). The snowshoes are made of a heavy cordura outer shell with an inner tube. Mine weigh 900gr for the pair plus the pump and bits for deflation etc, just under 1kg without crampons all in all. The crampons themselves are 236gr on my scale but look a good substitute for 10point crampons so I decided to use that configuration for my first test hike. The early morning snow was still hard but grippy at lower altitude and neither crampons nor snowshoes needed. Above 2000m, the snow got softer with wind drift powder and no longer any snow free patches. It was time to test the snowshoes. First thing I learned, its easier to attach the crampons before inflating them. But I quickly got the hang of getting set up and that was it. I didn't take them off again for the next almost 3 hours until a late lunch and brew break. I didn't see any human tracks all day and only saw trail markings occasionally. With trails buried I went cross country and oriented with GPS which took me through all sorts of snow and occasionally broken terrain, including climbing or descending through rocks sticking out which would have required removing rigid snowshoes whereas the flexibility of inflatable ones let me to just carry on. In summary, they are exactly what I hoped for. With about 4 hours hiking use so far, I've not discovered any flaws or problems. They are easy to walk in both up and down as well as traversing slopes and the crampons stopped any slipping and sliding effectively but there was nothing real steep where I hiked to test the limits. Surprisingly, my feet stayed pretty dry in just Brooks Cascadias. I carried a pair of sealskinz cycling overshoes as well as dexshell socks as backup but I set out in just the cascadias with merino socks to check how this would work but my feet stayed warm and comfy fir the entire time on the mountain with just a little dampness. Once inflated, they are small enough to strap to a pack, like the 25/38lt Nero I used today.
