These are small, light, simple, robust, and release at a reasonable value. I raced half-ish of last season with them and took them touring a few times combined with some Dynafit Radical toes. I had one lateral release in a race, stopping clumsily on icy chop. My technique sucks, and so did that hill, so I'm not calling it pre-release (and I ski with toes unlocked). I trust these skimo racing or mountianeering with lighter/shorter skis. Mind the heel gap, when mounting, as it's non-standard, and enjoy.
