The Normal Kjerag Brut has a fantastic outsole for muddy and wet slopes but you should expect premature wear if you run on more abrasive surfaces. The La Sportiva Mutant are a good compromise but not as light as the Kjerag
I have the same problem as you and the shoes that block my heel best are the NNormal Kjerag and various Salomon models such as the Genesis
As always it’s very personal depending on how well the shoe fits my feet and the terrain I’m running in (technical mountains, mud, rocky). I like sky running races around 20-30k and VK’s. Sometimes short road races from 5k to Half Marathon. Current rotation: - Merrell Long Sky 2 Matryx. Great allrounder. - VJ Ultra 3. Cushion. Great for easy and long runs. - NNormal Kjerag Brut (mud) - Salomon Aero Glide 3 (road and treadmill) Recently retired shoes: - Nnormal Kjerag 1. Fast but too small lugs to have good grip in mud/loose debris. Too little cushion for me. Kjerag 2 has more cushion but same outsole. - Nnormal Tomir 2. Great allrounder but didn’t fit my feet (too little big toe space). A bit heavy when wet because the insole keeps a lot of water. - Salomon S/lab Genesis. Great allrounder but worse grip on wet rocks than Vibram Megagrip and VJ. - VJ Maxx 2. Really good allrounder. But didn’t fit my feet (too little big toe space). Shoes I’m considering next: - La Sportiva Prodigio Pro - Merrell MTL Adapt Matryx - Merrell Skyfire 2 Matryx
I live in the UK and haven’t had too many issues finding places to try them on. The Tomir is a decent do it all shoe, capable of doing any trail run and some light fell imo. I don’t like it for rougher fell terrain as I find the stack really high (and the lugs are not that deep). I’m hoping the new Kieran Brut may be a bit better there (need to try them on) but I was saddened to see only 6.5mm lugs and seemingly a high stack. Points for durability. Would I take the Tomirs over my La Sportiva mutants as a do it all shoe, or my VJs? No, but I do like them quite a lot and those shoes I’m comparing them to set the bar very high.
Yeah, probably best option for the conditions we’ve had so far
Kjerag Brut has 6mm lugs and midsole is supercritical EVA. Very nice on muddy downhill, the toebox is not narrow but not as wide as Altra/Topo. You need to get 1/2 size down from your normal size. Also Norda just released 001A with TPEE foam and 5mm lugs.
I recently ran 50km with 1600m elevation wearing 'Nnormal Kjerag Brut' No complaints
Here’s my contribution. I haven’t done controlled tests like you did, but I run a lot of rocky vertical terrain and have put lots of miles in all these shoes. Trying to focus here on wet rock grip from the outsole and ignore other shoe attributes (fit, lock down, flexibility/stiffness, weight, cushion, etc) that also come into play with their overall ability to do the job on wet rock 5: VJ Maxx 1&2 VJ Spark Arcteryx Norvan VT (limited mileage) 4. Arcteryx Norvan SL 1, 2, &3 Salomon s/Lab Sense 7&8 Nnormal Kjeraq 3. La Sportiva Helios SR La Sportiva Vertical K & VK INOV-8 F-Lite 195 2. Whole bunch of older inov-8 x-talon and RocLite models NB minimus Salomon s/lab ultra 3 Salomon s/lab sense 7SG 1. Old Nike Terra kiger Salomon s/lab sense 1, 2, 3 For spiked shoes, I actually think they suffer quite a bit on rock because they don’t stick instantly like pure rubber soles. 4. VJ Devil 4 3. VJ bold race, VJ ice hero, INOV-8 ORoc 280
There is a new version coming out. I don’t think the changes are substantial though.
Yeah, the kjerags are a good option. I have a pair, but prefer the norvans for steep and technical stuff. Norvans are lighter and fit my feet much more precisely. Kjerag upper is a bit sloppy on me so my foot isn’t as secure as I’d like for rocky downhill stuff. Kjerags definitely have a little more cushion and “pop” to the midsole, which is nice, but not enough cushion or outsole grip that I’d reach for them over my preferred all-arounder: VJ maxx2
My recommendation would be the VJ Maxx2 I also really love Arcteryx Norvan SL3 for steep technical uphill stuff, but these are maybe a bit too minimal for a lot of people’s taste and I think they’re discontinued. Bought a pair of Vertex Speed Low to try as replacements? But they’re not really the same. You could also try Nnormal Kjerag. This kind of splits the difference between the two shoes I listed above. I found the upper to be a bit too sloppy (foot will move/roll relative to the sole on off camber stuff) compared to the other two though, so I don’t trust them at speed in serious technical terrain. That’s pretty specific to my foot though, otherwise I think I’d be a big fan.
My go to for this is the Arcteryx Norvan SL3. They might be discontinued though. I recently picked up a clearance pair of Merrel Skyfire 2 Matryx that see very very promising. Never owned a merrel shoe before, but excited for these this year. Wouldn’t be my first choice for pure rocky trails given the lack of surface area in the lugs. Another similar shoe is the Nnormal Kjerag. I don’t love the fit. Seem a little too sloppy in the upper midfoot for my taste on really technical terrain, but everyone’s feet are different. Common theme among those - lightweight, matryx upper, megagrip sole. I find that to be a good recipe. You could also check out VJ Spark. I put a few hundred miles on a pair, but honestly I wish they had more rock protection and a less bulky upper. VJ Maxx2 is a great all around shoe. It’s not heavy, but not super light either.
I don't know about hybrid shoes, but for trail I've settled on Nnormal shoes. I have the Kjerag and love them. They also do a softer model, the Tomir, that I'm eager to try. I would highly recommend having a look at them.
got the Kjerag. Rubbish grip for 80% of the trails i run in the UK. Fun, light shoe to run in though. They are in the cupboard for some dryer days out. Just accept Innov8 shoes are what you need for the UK, even though they look terrible.
