Nike Infinity Run might not be the most trendy shoe in the world but they last forever. I'm about to hit 1000km in my 1st gen pair (which I bought when they were first released in 2020? 2021?) and they feel as fresh as a brand new in box pair I bought last year. The FK4 have also been doing me really well this year and are currently sitting at about 400km and still feeling great, though I don't like the upper as much as the FK1.
I have the Clifton 9 GTX and it's the same experience, but I'd much rather be running in the infinity run!
I personally tend to have different shoes for different terrains and weather rather than specific workout/run types, which might not be the 'best' way to go about it but is what works for me as I live somewhere with a very changeable climate. I have shoes for road-to-trail (Juniper Trail 3), shoes for wet weather (Hoka Clifton 9 GTX), my daily drivers that are just fun to run in (Saucony Ride 18), and then a couple of pairs of Infinity Run Flyknit for my long runs - the FK1 for hotter weather (the upper is basically a sock) and the FK3 for cooler days. I've got a half marathon booked in in October and I'm considering picking up a new shoe specifically for that race but that's more because I like buying new shoes than because I feel like I actively need it.
I do all my running in Nikes. They have been good to me, especially the IR1,2, and 3’s.
Do you do the 20k per day so in the same shoe or is it doubles? I use the neovista for long runs and other shoes for a lot of my others so get longer out of it. Weirdly my shoe that lasted me longest was Nike react infinity, 1400km on that but it wasn’t a long run shoe for me so probably only did 15km at a go max. I think the vomero is meant to have taken the place of that now they’re off the market. I’ve a lot on the first cloudmonsters and while they’re fairly vanilla they’re good, never feel beat up in them and high stack but still a bit firm, I don’t like overly squishy and heard the second version is squishy /nimbusy which I feel taxes my legs too much at longer distances.
I've been running in Nikes for years, and what you're describing sounds like the Pegasus line - solid all-rounders that work for most of my runs. If you're looking for something with a bit more responsiveness for those zone 3 efforts but still comfortable for long runs, I'd suggest trying the Nike Invincible or the React Infinity. Just make sure to try them on first, as Nike's fit can vary between models.
Pumagrip is said to be the king of the grip. I personally have very good experience with Continental rubber. Actually old Adidas shoes worked very well for me for a long time. I'm not sure about the new models though. And you want something built like a tank, so nothing from adizero lineup. A shoe which in my case still look good and go strong is Nike Infinity Run. The exposed react foam surprisingly shows no wear at all. Flyknit on the upper also is in perfect condition. I only stopped using them because they were to firm for my liking. Now they serve me in the gym. Have you looked into rugged versions of ordinary shoes like NB fresh foam more trail, NB Hierro or Nike pegasus trail?
If you can find any, the Nike React Infinity Run Flyknit. First version were the best ones. One of the OG long run shoes. They could do it all.
Definitely hit up a running specialty store if you can - they'll analyze your gait and let you test different styles. I was completely lost when choosing my first pair until I went to my local Fleet Feet where they helped me find that Nike React Infinity Runs worked perfectly for my slight overpronation. The best shoes are the ones that disappear on your feet when running, so take your time trying several pairs and trust your comfort over anything else.
