I was a vapor guy forever and switched to Machs/Supremes a few years ago. The injected eyelets suck and feel nothing like the glory days tech mesh vapors. The Mach has way more flex in the ankle. Might not be the solution for you but I’d try a fit 1 if you can find it to see how it feels. Jetspeeds would be another option. Imo the current Vapors are only similar to your X60 in name only.
Alternatively you could try to find pair of pro stock V cuts which are essentially a reskinned X60.
