Should I upgrade after Shin stress reaction?

Intro: Hi, as stated I've been having shin pain for the last half of the previous season. I suspect a stress reaction as the bone also started hurting where it was only tendon-based beforehand.

Bio:

• Age: 24 y/o

• Gender: M

• Length: 1m80

• Weight: 88kg (suspect around ~21% bodyfat)

• Shoe size: ~44.5 EU

• Flat feet, x legs

I've played the last half of previous season with a pair of Asics Netburner Ballistic FF 3 MT.
On my recent running analysis, the sports physio said I'd be better of with shoes that have more inner foot activation and greater dampening.

My research brought me to the Sky Elite ff 4, but they seem quite pricey to buy on a whim. Can anyone in a similar situation / that is more knowlegable than me make a recommendation? :)

Thanks in advance!
