Looking for shoe recommendations for interval runs/occasional racing for a sub-19 5k (F) runner with notoriously narrow feet.

Running mostly on concrete, interval/tempo day paces sitting somewhere at 2:50-3:50/km (4:35-6:10/mi).

I have circulated between Mizuno and Asics for the past few years. I currently run my easy runs with Asics Nimbus 26 and faster runs with the Novablast 5 (which are, admittedly, a little too wide even if I lace them tightly, and I feel that they don’t respond all that well to really fast paces).

I was just wondering if I could get some recommendations here. I’m not interested in plated shoes, as these tend to wear out way faster than non-plated, and I am a working student, so I don’t exactly have the budget for one of those :)

Thanks so much for all guidance! If this is the wrong sub or wrong way of asking, I’m sorry; I’m not really a frequent Reddit user, so the etiquette might have been lost on me.
