Dynafit has long been equated with efficient and fast backcountry skiing. First their bindings and now TLT boot line and skis have become THE standard. It was only a matter of time before they entered the mountain running game and that time is now.
The MS Feline Superlight is their first attempt at a high end trail running shoe and fortunately for us they nailed it. To me, a mountain running shoe should be able to tackle any type of terrain, be it dirt, talus, easy 5th class rock moves, etc. As far as weight is concerned, it should be on the lighter end of the spectrum but not so minimalist that every rock is noticed or that so little support is provided that one ends up injured and out of the game. It should have excellent traction without being an over built monstrosity. I think a good guide is if it can be used to run on the road without noticing that it's really a trail shoe. Obviously, durability is an issue so quality construction is key. And lastly, the fit has to be perfect. With the degree of climbing, descending, rock hopping, and multi directional movement, a poor fit at best leads to huge blisters but can be a harbinger of injury.
Out of the box, one notices that the Feline Superlight meets the above criteria. I've used it so far on dirt, rocky trails, scree, and boulder hopping and it excels at all types of mountain running. I've used it on road runs and find it on par with a dedicated road shoe as well. With some shoes, it's apparent that they will fall apart after one really long demanding run but so far there are no signs of appreciable wear. Perhaps most importantly, the fit is perfect without the slightest blister thus far. I'll for sure be using it for all my future races, adventure runs, and ridge scrambles.
