If you're a La Sportiva fan and love to run on gnarly trails (mud, rocks, steep grades, etc...) then you'll love this shoe. Be prepared as it is very low profile and the midsole isn't as thick as a traditional trail running shoe so you will feel the ground and what's under your feet. There is a built in rock-plate that does help mitigate this feel somewhat, but it also makes the shoe quite stiff. Overall the shoe has great traction though was not very effective on some of the slicker, wet rocks I typically run on (polished limestone), but then again nothing is too good on the wet rocks around here. The lace corset isn't the best feature, in fact myself and others typically just cut the thing off to gain access to the laces easier. Also, a common issue with trail shoes that utilize a lot of fabric mesh on the upper, they tend to tear up at the metatarsal flex point in the shoe, both pair I owned did this after just a couple hundred miles.
Overall this is a good, no nonsense, serious trail shoe that will work for most trail runners.
