RIBELLE RUN 2

I've tried everything you mentioned except the Lowa's (I've even worn the cork Sole insoles). It's a crying shame that LaSportiva can't widen their toe boxes!!!! Two shoes worth your consideration per my efforts are: 1. Scarpa Ribble Run 2 (sizing is weird, must try on, not the same as previous Scarpa models). Toe box is more generous than LaSportiva, but not Altra. Very durable and good traction, not heavy.  2. Altra Timp BOA 5 (I've only tried BOA version, lace version may be fine) This version of the Timp has Vibram, Altra width and actually more like the Olympus than LP. Previous Timp models did not do it for me, this one is worthy.  I know nothing about the Flux footwear,  but am now curious. 

I too have gained appreciation for the Scarpa Ribbelle Run. Have tried most all the other usual contenders too, Ribelle Run is current fav.

Scarpa has most of their shoes in 14US. I’ve the same size and have Rapids and Ribelle Run 2, as well as a couple of pairs of boots and casual sneakers, made by Scarpa. They do tend to fit narrow, which is exactly what I need, but not everyone

I've used Prodigio Pro for alpine terrain and it works. However, midsole takes a lot of damage and it's not super durable for rocky terrain. I mostly use Scarpa Ribelle Run 2 for alpine terrains and scrambling, more than enough protection around your feet and excellent grip.

Looking for some experiences :) Looking for new shoes that bridge between approach shoes and trailrunning shoes - essentially trail running shoes you're comfortable doing class 4 scrambles/climbs with. I've tried Scarpa Ribelle Run 2, and while they are really great for this, my feet hurt as they are just too narrow for me. Otherwise these would be like the perfect shoes for me. Great damping on the heel but a stiffer toe area for those sketchy parts is amazing Arcteryx Vertex Alpine is another one of these, but apparently that one's even narrower...

Do you think sportiva tx2 has enough cushioning in the heel? I can really recommend the ribelle run 2’s except that they’re just not wide enough for my feet. Which i’ve learned after getting blisters on the same spot for the 4 times i’ve worn them :)

In my limited experience vibram megagrip were ok at best on wet rock, very bad on wet dirt (not very muddy). Best ones I tried were Scarpa presa.

I used Scarpa Ribelle Runs for easy scrambles (UIAA grade 3 iirc), any shoe designed for sky running will work decently well

Gravel is a tricky surface, I agree. It probably depends on the the percentage of a certain terrain in a run that I choose the shoes. Generally, for steep grass I like Mudtalons with 8mm lugs, for snow the Genesis and for barely runnable rocks Bushidos. But then again, there is always a trade-off, since a run is usually composed of different surfaces. As an allrounder in alpine environment, I often go for Dynafit, Prodigio or Ribelle Run. YMMY. (And yes: I might have too many shoes).

I have been running in the Italian Alps for about ten years with distances even over 100km. I think that's enough to give you some advice. It really depends on where you live, the terrain you train on (mud, gravel, rocks, roots), the distance you like. To start, however, I recommend a comfortable shoe with a 4-6mm drop that is not excessively cushioned (you lose a lot of sensitivity on the ground) a sole with not too large notches (if there are some fast areas) Hoka Mafate Speed, New Balance Hierro, La Sportiva Akasha, Nnormal kjerag. Salomon sense ride (cheap and fast) Now I'm using the Scarpa Ribelle Run, they have 500km but they're not good
