His feet, on the other hand, were miraculously dry. And that wasn’t the first time the SCARPA Ribelle Run Kalibra G winter trail shoes impressed Bergen. That said, both gaiters offer excellent protection. The Cyklon sports a GORE-TEX gaiter and surrounding membrane, whereas the Kalibra utilizes Polartec Windbloc. Neither of them claims to be completely waterproof. But they both exceeded our testers’ expectations in both breathability and resistance to the elements.

The midsole provides a good level of cushioning. This is soft at the heel and firmer in the forefoot to allow for a strong push off. The overlay in the forefoot of the upper completely covers the midsole in the forefoot. This not only protects the EVA from abrasion but stops it squashing outwards when you put pressure on it. This gives the midsole in the forefoot more rebound and therefore more propulsion.

There is about ¾ of a UK size between European sizes. The Ribelle Run fit a bit on the big side. I have a Euro 46 and usually wear a Euro 46.5 in most brands. In my experience the Ribelle Run size half a Euro size larger than most running brands, so I would suggest trying half a size smaller than you usually use. Stretch fabric ankle collar incorporated with a minimal stretch tongue provides gentle wrapping and support, reducing bulk and enhancing fit, and seals out trail debris. That makes a big difference. Heel lift, which often plagues other BOA footwear, is a non-issue for the SCARPA Ribelle Run. Detailing on the new SCARPA winter trail runner; (photo/Katherine Murphy)

The former felt a little sharp, and I found myself wanting a little more precision, although a part of this potentially comes down to the fact I was having to over-tighten due to the sizing issue I was experiencing. Summary The SCARPA Ribelle Run Kalibra G runs far more pleasantly on moderate terrain than either tester expected, given their burly sole. They roll naturally and are plush enough to push the mileage. The gaiters are not restricting in the slightest. Bergen runs hot, but reported that his feet never overheated or got clammy, nor did they get soaked by the snow — which was a notable victory for this shoe. Testing the SCARPA Ribelle Run Kalibra while trudging through snow; (photo/Bergen Tjossem) Mary didn’t experience any wet feet during her testing of the SCARPA Kalibra G, either. So, while the holes under the BOA knobs look like exposed openings in the gaiters, they seem to seal up just fine during use.

The gaiter material is Polartec Windbloc, which promises a balance of water resistance and breathability. Both testers found that to be the case out on the trail. Lightweight, breathable mesh with overlays of thermally welded PU film and translucent ripstop holds foot securely in place and provides support and protection.
