Combining BioMoGo cushioning with a mild support post, the smart, adaptive Ravenna meets your changing needs. Some runs demand more support than others, so the Ravenna provides just the right amount, when and where you need it. Hardworking feet swell after a long flight or day at work. Extra adjustability in the Ravenna’s upper means more instep variability for a perfect fit, every day. Brilliant. Weight: 10.8 oz.
