In the last few years, Kastle has released Limited editions of their famed MX84 numbering 500 total pairs each season. The plan was a winner. For 2019-2020, they're bringing back all three Limiteds, the Supra, Scala, and Proto, with new beech topsheet veneer for the latter two. The Proto is the most similar ski in the family to the MX Limiteds of years past. At 83mm underfoot with titanal in the build and traditional camber throughout, it's an on-trail-oriented, feel-good speed machine that skis smooth and plush as velvet. Compared to the regular MX84, the Proto is lighter and more damp, offering an even more buffed-out premium experience. The oak veneer and carbon topsheets pay homage to past Limiteds, while the elegant white copper wire reminds you that Kastle hasn't been resting on their laurels.
