A comfort-first daily cruiser for easy road miles, defined by its cushioned Boost ride rather than any speed pretensions. Best if you value all-day plushness over snappy turnover.
Soft and cushioned underfoot with a tall 38 mm heel and 10 mm drop, leaning toward comfort over responsiveness despite the lighter Light Boost foam.
Snug, sock-like Primeknit upper with a regular fit; most runners find it true to size, though the wrap can feel tight for wider feet and only standard width is offered.
Easy daily runs, recovery days, and walking where comfort and cushioning matter more than pace.
You want a fast, propulsive shoe for tempo or race efforts, or you have wide feet and need more room than the snug knit upper allows.
