Purchased for the 2025 Osaka Marathon (January '25). Size: 28.0cm. I usually wear 27.5cm in Nike. I tried them on a few times before the race and used them only once in the actual race. Total distance is about 70km. They are D width, but those who can wear regular width Nike shoes should have no problem. I decided they didn't quite fit, and haven't used them since. These shoes have good reviews on YouTube. Here's the manufacturer's description: If you're looking for speed, choose UA Flow. It uses no rubber, which adds weight, and features the latest lightweight and durable cushioning. It grips the ground firmly, improving grip and speed. You can experience speed as if you have a tailwind. Features a built-in fiberglass plate, a plate-assisted lightweight model. UA's unique upper technology, Warp Upper, acts like many seatbelts on the foot with horizontal and vertical tape lines, providing foot lockdown and lightness. The simplified heel structure eliminates unnecessary elements, providing the heel lockdown runners need. A full-length fiberglass plate provides rebound, resilience, and excellent propulsion at toe-off. PEBAX FOAM: Foam placed above the plate. Lightweight foam that provides a very soft landing and excellent elasticity for energy return. SUPERCRITICAL FLOW: Foam placed below the fiberglass plate. Evolved into a softer, lighter, and more responsive foam through supercritical fluid foaming, providing an unprecedented ground feel. FLOW technology eliminates the need for a rubber outsole, creating a lighter and more seamless ride across the entire sole. FLOW is also durable as an outsole material, dramatically improving ground traction. D width. FLOW: A sole unit made only of lightweight, responsive, and grippy cushioning foam that fits the movement of the foot and provides an unprecedented ground feel. #HOKA #Nike #puma #salomon #asics #adizero #Boston #magicspeed #fuel #Pegasus
