La Sportiva Women's Helios

Backcountry.com says:
Run far and fast into the wild when you're wearing the La Sportiva Women's Helios Trail Running Shoe. Designed with the performance trail runner in mind, this little beauty feels nimble underfoot and smooth over rough, rocky surfaces. A wave-like midsole structure helps the sole adapt to uneven terrain and absorb impact while the low heel-to-forefoot drop allows your foot to naturally roll from heel strike to toe off. Over medium-to-long distances the Helios saves your foot and joints a thrashing. La Sportiva calls this a minimalist trail running shoe and, due to its feathery 8. 1 ounce weight, it would be hard to disagree. Only two of Sportiva's other mountain running shoes compare, the Vertical K and the Anakonda. The Vertical K is a few ounces lighter at the cost of cushioning, while the Anakonda is lower to the ground with a more aggressive grip. While both of these shoes offer distinct advantages, the Helios brings the the best of both worlds, striking a balance that allows you to tackle a mixed-terrain 10k or a marathon through the woods.
