Winflo 12

The Winflo 12 is a complete redesign. Nike has given its budget trainer a wide, max-cushion platform, close to the first Puma Magmax Nitro in shape, with Cushlon 3.0 foam and a full-length Air unit. The softness is balanced rather than plush, more protective than bouncy, and the stack height feels high, but the shoe doesn't feel heavy on foot. On a first 10 km run it felt stable and protective at slower paces (over 6:00/km). It's a neutral shoe, not a stability shoe, for neutral and high arches. The upper is now a thin, breathable mesh, fixing the Winflo 11's breathability issue, with a full gusseted tongue and a thick inner lining that should protect the mesh from tearing. The outsole rubber is thinner and softer than usual for Nike, which keeps the weight down but may wear quickly on hard tarmac and lose grip in the wet. It runs true to size. I went up half a size for a full thumb-width of toe room. Leave a thumb-width of space so your toes don't punch through the mesh.
