Launches sometime in October 2013. Even though the shoes have not released yet, Extreme Supply is already offering to let people order them ahead of time
Uses Evofiber, unlike the previous version (2012 model) Teijin AG100 microfiber. Supposed to be lighter material. According to Arts Cyclery, it "fuses the best attributes of mesh and microfiber to create a fabric that repels water, improves breathability, increases durability and lowers weight" and "supposedly doesn’t stretch, yet remains supple"
The 2 little bolts in the heel pad looks like Giro listened to customer feedback and realized they want replaceable heel pad, which was missing in the older Prolight SLX model. Good on Giro.
The EC90 sole looks even more sculpted to shave more weight too.
Old ones weighed in at 410g/pairs, new ones are at 205g each, so same weight. Way lighter than Sidi Vent Carbon too.
The matte black with white strap over the middle looks awkward (trying too hard to be the poor man version of the Rapha Grand Tour, which is also made by Giro), but the other colors look good. I was hoping for an all matte black one.
