I wonder if the foam cushioning of the Zoom Fly 3 would add protection to the achilles?
Looking at Arena80's Half Marathon results from Sunday I noticed a few fast times from people in my time bracket and thought they'd run well. Yesterdays photos showed Vaporfly on each and everyone of the outperformers.
My Next0% are still in the box unworn. Today's sunshine and dry ground was going to be their maiden trip but I will stick to my rule of not running 3 consecutive days especially with an interval session.
I don't know - are Achilles issues caused by impact, specifically? I'd assumed, in my case at least, it was over-use (again).
