As per the comments in Fit, I wasn't a fan of the speed lacing, but do like the traditional laces supplied. 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

Fit: The shoe is built to wrap the foot with precision thanks to its reduced volume fit, perfect for this more technically oriented shoe. The heel is stabilized by an EVA band that completely wraps the shoe. 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. The Ribelle Run trail running shoe is for those who are looking for absolute precision and high adaptability on any degree of difficulty or type of terrain. It is designed for short to medium distance trail and skyrunning. This lightweight, high performance shoe is perfect for athletes who are seeking sensitivity and precision on rough, technical terrain. Lightweight, breathable mesh with overlays of thermally welded PU film and translucent ripstop holds foot securely in place and provides support and protection. 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 Ribelle Run GORE-TEX trail running shoe is for those who are looking for absolute precision and high adaptability on any degree of difficulty or type of terrain. It is designed for short to medium distance trail and skyrunning. This lightweight, high performance shoe is perfect for athletes who are seeking sensitivity and precision on rough, technical terrain. The other advantage with the speed lace is that they don’t get untied by the undergrowth as you run or go crusty when mud gets dried into the lace.

Usually, we try to get 150 miles on a shoe before writing a review. Due to factories being closed because of Covid infection we had a longer 6 months to test run the shoes. That means we can write a bit more about the durability of the Ribelle Run. The first thing I would mention is sizing. Ordinarily I would expect to size up with a running shoe, maybe by half a size to a size depending on the shoe. With the Ribelle Run I would warn against going overboard, as it feels quite generous in terms of both its sizing and its fit, and it's probably worth going with your standard street shoe size at least to begin with, then go up (or potentially even down) from there. 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.Both Mary and Bergen tested these shoes all over in the Colorado snow, both on maintained trails and off-trail. Wearing these comfortable, secure shoes before they needed to strap on skis or crampons was huge. You've got to assume the GTX version weighs at least a little more than the unlined original, but I can't offer you direct comparison since Scrapa's weight figures online refer to different sizes. For the waterproof shoe they say 520g for a pair of size 38 (presumably this is the women's version since men's starts at 40 in the UK), while my much larger pair of size 47 weigh considerably more at 764g. Still I'd consider this midweight for a shoe, certainly not outrageous for a long day on your feet given the cushioning and support on offer (to say nothing of the waterproof membrane). Hoka Speedgoat: The cushioning is a bit softer but, you lose the feel for the floor. So, the Speedgoat doesn’t feel as nimble as the Ribelle Run. The Speedgoat is a bit more bouncy in feel. Here is our Speedgoat review: https://www.northernrunner.com/blog/hoka-one-one-speedgoat-evo-review/ 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.

Another reason they feel a little larger is because of their wide fit, particularly across the forefoot. This is accompanied by quite a high volume around the midfoot. If you've historically had trouble finding shoes that fit your wide, chunky feet then these will potentially be the holy grail you've been looking for.

SOCK-FIT SLIP ON

It took me some time to figure out exactly what was the source of the issue with the Ribelle Run’s ride, and after over 100+ miles, I think I’ve gathered enough anecdotal evidence to speculate. The problem starts with the stiffness of the midsole; instead of delivering high amounts of energy return, the EVA feels both inflexible and unresponsive. I think swapping out the existing midsole with one that is lighter and more cushioned would benefit future iterations of the model, which is otherwise tremendously well made, in my opinion. The Ortholite insoles Scarpa uses do add some plushness to the overall feel of the shoe, but not enough to offset the harshness I felt from its otherwise rigid platform. Technical trail shoes do generally need to be built studier than models intended for general use, but I think the Ribelle Run would be just fine without Scarpa’s “Dynamic Stabilizer Torsion” frame as well. The DST frame is included in the shoe’s midsole and wraps under the arch before extending along both sides of the heel for added stability and torsion control, but in my experience, it interfered with my natural footstrike by being too restrictive. Juggernaut” (SCARPA’s term) is an appropriate word to describe the Ribelle Run Kalibra G. It’s a burly shoe that’s hungry for challenging terrain. SCARPA’s designers were clearly inspired by mountaineering footwear like their Ribelle Tech 2.0 and Phantom series.
