Thomas gives you a little history lesson the Zoom Fly before we dive into the review with Robbe and Brandon. Not much has changed over last version aside from an improved upper, so those who loved that version will love this version. But if you’ve stayed away due to that heavy React slab underfoot, you’re probably not going to want to jump in on this. A divided review for sure, but hey – that’s how we roll. Carbon plate, React midsole, engineered mesh upper. Weighs 9.6 oz. for a US M9.0. Drop: 8 mm (39 mm heel, 31 mm forefoot).
