The Gabrielle pump by Ara is a part of their High Soft collection, which means these will be about as comfortable as a heel could ever be. The patent leather uppers are very soft and leather lined, while the padded leather footbed sits atop a very comfortable ~1.5" block heel.
Available at Glebe Trotters.
*These are built on Ara's H last, meaning they are a bit wider fitting than your average pump.
