The shoes feels going slightly into the F50 size and shape, hope the narrowing ends there with this model. The red is really going towards hot pink, which is mostly annoying cause feels like marketing misleading. The biggest issue I have with the shoes is after 1 training day the sole seems to be already separating, glueing the area and applying a protective layer in the area, but still 1 training day. On the performance aspect the shoes feel more comfortable than previous models, the material around the heel and thicker fold makes it feel like you are wearing a warm and cozy blanket, while the rest of the forefoot is in killer mode with great feel for the ball, that balance well that “too sticky not sticky enough balance”. The spine, cool very cool, power delivery increased? Maybe but honestly is soo cool I wouldn’t care, keep that forever adidas
