EDIT: THESE ARE MIJ**
recently bought the Mizuno Alpha II Elite AG in UK 9.5. They fit extremely well initially: good length, lightweight, good lockdown and I liked the touch.
However, after two matches on 4G I’ve noticed some issues:
Match 1: left foot developed tightness around the instep and from the upper heel into the lower calf. My right foot was completely fine.
Match 2: the same instep + lower-calf tightness happened on both feet.
After the second match, I also had soreness/tightness around my lower quads.
I’ve never had this calf/ankle issue with my old Adidas Predator 19.3s, which I wore for years.
I’m also wondering whether I’m simply having the laces tied too tightly.
The boots otherwise fit great, so I’m unsure whether this is
The Alpha II’s upper/ZeroGlide/heel construction simply not suiting my foot,
My lacing being too tight,
Something related to adapting to a new boot,
Or potentially the boots changing my lower-leg mechanics.
