We recommend the Ulla Johnson Esti Clogs as a stylish and comfortable option for your evolving wardrobe during the first and second trimesters of pregnancy. These clogs boast a stable 2.25-inch block heel, providing a subtle lift without compromising balance—a key consideration as your center of gravity shifts. The open-toe design is fantastic for accommodating minor swelling and ensures breathability, while the calfskin upper should offer a soft, flexible fit that won't constrict. The adjustable ankle strap, though buckled, allows for a customizable fit as your foot changes. They work beautifully as a wardrobe staple, easily transitioning from casual daywear to more refined vacation looks. While the buckled ankle strap might pose a challenge for bending during the third trimester and postpartum, their overall comfort and stability make them a chic choice for earlier stages.
