I’m a big fan of the Topo MTN Racer 3. I haven’t tried the MTN Racer 4 yet. Just did a 20 mile trail race on similar terrain and the shoes were fantastic. They have similar drop and a similar toe box and mid foot to the Altra Experience Wild.

Well, I did a short run in these on the treadmill this afternoon and they're not gonna work. The midfoot is just too narrow and uncomfortable, especially with the pronounced arch. I could feel it just pushing up into the side of my foot. It's like the side of my foot is just hanging over the narrow part of the midsole under my arch. Such a shame. I really dig the look of the shoe and was hoping it'd be the right choice for me. I do my long runs on the trails and am preparing for some 50k races next year. I need something that just disappears on my foot. I don't want to be thinking about hotspots or blisters or feeling something unnatural. That said, I did notice Topo makes the MTN Racer 4 in a Wide. I ordered that and hopefully it'll give me the width I need in the midfoot without making the toebox too big. Will post back here with an update after I get the 4's. Supposed to be here on Sunday.

I have this exact issue with mine. Overall I love the shoe, but I get a blister on my right foot, exactly where the arch meets the ball of my foot. I’m considering custom insoles but have no idea what to get

I have giant arches so they are a beautiful fit for me. The arch support pays off especially long distance. Never had an issue with blisters in them.

I do all routes up to class four in trailrunners. Ive never felt like theres enough middle ground for approach shoes to me, its runners up to class 4 maybe very low 5th, then climbing shoes for anything above that. for Love Topo Mountain Racer 3 right now.

I'm on my second pair of Topo Mountain Racer 3's, and have used Altra Lone Peaks in the past, but I have no idea what will work for you. There are many options that will do the job, you just need something that fits you.

Asics trabuco is quite wide. Topo MTN racer 3 is too narrow for me too, mostly due to the midfoot

I wouldn't go for the pegasus for the activity you describe. If I'm not wrong Nikes own outsole it is not good if you get rain (haven't try it myself). I tried topos MTN racer 3, it is nice and I think they could work, but midfoot is too narrow for me. Maybe you can try them. Lug pattern seems good for rocky terrain and they feel quite light and enough cushioned.

Asics trabucos are wide and roomy. The speedgoats 2E are actually very narrow and low volume. Even the mafate speed 4 in normal width are roomier. I tried topo MTN racer 3. They are wide in the forefoot, but narrow in the arch/midfoot. Can't wear them Agility peak 5 is also wide and high volume.

I had same problem with speedgoat 6 wide and Topo mtn racer 3, among other lot of shoes. Mafate speed 4s are a little wider/more volume than the speedgoats if you want to try hoka. I dont run on them more than 3 hours because they still feel narrow to me and cant size up more. Shoes that fit me well and could work for runnable with some technical sections: Asics trabuco 13s: My do it all shoe. From runnable to really technical, the upper gets ripped of easy. Not tall, not too soft but still cuishioned. I have run on them 10+ hours race in very technical high altitude terrain. Asics fujilite: If you are not heavy they could work. I use them for shorter racers and high intensity workouts. Very confortable, but dont have a rockplate and you could feel too much ground if the terrain is rocky. Merrel agility peak 5: Easy running and can handle some technical sections. Dont know if the 6 fits in the same way. Nike Zegama 2: Confortable for easy to moderate terrain. Too soft for really technical stuff in my opinion. Fits nice. Sportiva Akasha 2 and tomir 2: Maybe not the best for the runnable sections, but nice on the technical ones. They are roomy and confortable. I havent tried them but thinking of getting a pair of mount to coast T1 for this years big objetives. They are supposed to be roomy and confortable for long races.

Lowish stack, good grip outsole and not too soft. I have a quite difficult foot and not much shoes fit me well. I use to take for this kind of races trabuco 11 and 13. I would try tomir 2.0, akasha 2, trabuco, mafate speed 4/speedgoat, slab genesis, Topo MTN racer. This year im running 45km +4.000m in high mountain very technical terrain and im thinking to try the mount to coast T1. Last year I did a similar one, 43km +3.700m/-4.000m with the trabuco 13s and quite happy with them, i ended with "fresh" legs.
