I bought these sight unseen in a "hail mary" effort to find strong stable walking shoes before leaving on a trip where I'd be walking on cobblestones with an injured knee. While the American Podiatric Medical Association doesn't appear to formally recommend shoes, they do issue a "seal of acceptance," -- Vionic is on the list and Amazon could deliver before the trip.

Yay, success! This stable, supportive walking shoe immediately reduced pressure on my knee, particularly when going up and down hills and stairs -- and also when moving laterally as we tend to do on cobblestones. They were a tiny bit larger than I would have liked, but fit closely enough that all was well. I recommend this exact shoe and would buy another pair in the future. I haven't had them long enough to know how well they wear over time.
