I think “neutral” tends to refer to pronation - side to side movement of your foot. Whereas mid foot / heel strike is about where you land.
Easy to check though if you have a look at your shoes and see where they wear. A heel striker will see lots of wear on the heel (obviously!) while mid foot will have minimal wear on the heel. My shoe wear first on the outside ball area - behind the little toe, which is the first thing to hit the ground, for example.
Hmm, not hundred per cent sure but possibly ultraboost. I'm a neutral runner so neither heavy on the toe nor heel.
