The redesigned upper pairs breathable mesh with a stretchy knit construction, which means airflow where you need it and give where your foot moves most. It's a practical combination that keeps the fit comfortable and secure through daily training without feeling restrictive.Why Our Fit Experts Love This Shoe""I put the Neo Zen 2 through a tempo run and was genuinely surprised by how well it held up when I picked up the pace. The cushioning felt balanced - supportive without being soft to the point of feeling spongy - and the heel transition was noticeably smooth. It's the kind of shoe that just gets out of the way and lets you run."" - Sullivan, Road Runner Sports Fit Expert, Naperville ILWho It's Best ForIf you're a neutral runner looking for a road running shoe that handles both easy days and faster training runs without compromise, the Neo Zen 2 is worth a close look.
