Third shoes

Hy, every1 Currently I use two pairs of shoes (Mizuno wave inspire 20 & Asics kayano 30; Stable and cushioned shoes, with high drop). I'm looking for a third pair of shoes to use for fast workouts (<4:30 min/km) or for technical training (repeated) and/or for races. I have a neutral foot with a tendency to pronate, but I prefer to wear stable shoes. I run at about 4:30-5:00 Min/km. I run on asphalt. Generally I run about 10-15 km, my race comfort zone is half marathon & 10 km. Budget no problem. Any advice?
