Rothy's makes two different flat styles: rounded toe flats ($125) and pointed toe flats ($145), letting you decide between a versatile, everyday flat or something better suited to polished occasions. They come in a variety of neutral and bright colors, as well as flashy prints such as a spotted leopard print. These colors and prints rotate out from time to time, so there are always new ones to choose from. The colors of the insoles depend on the style — sometimes they match the uppers and other times they don't. You can also buy extra insoles in different colors here.
An easy way to identify Rothy's flats are the blue stripe at the heel of the shoe and the knit fabric. Both flats have an angular, V-style opening, which can help your feet look longer or more slender.
Allbirds makes one flat style, the Tree Breezer ($95), currently available in four colors. Allbirds has a history of releasing limited-edition colors quite often, so check its site, social media, or the Insider Picks page to find the latest options.
Its flat has a rounded toe and rounded opening, with a mesh knit fabric that's more noticeable than Rothy's. The "collar" of the opening is also more obvious and is made from a ribbed knit, so it hugs your foot more closely. The insole is Allbirds' standard gray insole.
