I have been buying the same style for years, at least 7 years, in different colors, for work. The older version had buttons that would come off. The new version with a strap is better. This is the only shoe I can wear with my bunions so I order multiple in case they stop making this exact style. If using the same "mold" they can make more designs it will be great, though this is just fine too. i have noticed that the material is not so strong any more. The finish gets worn out pretty quickly. But for comfort I will continue to buy it.
