Tom Pritchard wrote a review of La Sportiva Helios Trail Running Shoe - Men's on November 19, 2013
Familiarity: I've used it several times
Fit: Runs small
Good light trail runner with some cushion but not too much. I haven't put these through the wringer yet but like them so far. I have worn through pairs and pairs of Wildcats but wanted less drop, the Helios offers that in a lightweight shoe. Beware, it runs really small. I wear a 45.5 in the Wildcat and had to go 46.5 in the Helios. Normally I wear an 11.5 street shoe and 12 running.
