One stays in my rotation, and the other is being moved on. In this head-to-head comparison, I break down why these two "Super Trainers" have one critical difference despite their similar specs. We dive into the battle of the foams— FF LEAP / FF Blast+ vs FF Turbo Squared—and I explain why one of these shoes caused me knee pain due to my flat arches and overpronation. If you are a overpronator or looking for the perfect marathon shoe for 2026, this deep dive into stability, stack height, and real-world use will help you choose the right "Blast" for your miles.
