These are On Running Cloud 5 womens sneakers in a Glacier blue and slate colorway, labeled US W8 (EU 39, UK 6, JP 25). Built with On's signature CloudTec sole technology featuring hollow cushioning pods for soft landings and firm push-off, the upper combines breathable engineered mesh with perforated suede-like overlays for structure and ventilation. The tonal lace system, dark slate collar lining, and Swiss flag badge at the heel tongue reflect On's signature minimalist Swiss engineering design.
