Fit Tip: Clogs and sandals usually have a roomy fit. If you are between two EU sizes, choose the larger size for a more comfortable fit.

Size conversions are approximate. Foot shape, width, and fit preference can affect the best size choice.

The Boston is Birkenstock's classic slip-on clog — a closed-toe shape with a single adjustable strap across the top. It's a straightforward option for cooler days or indoor wear, with a bit more coverage than an open sandal.

It's built on Birkenstock's contoured cork-latex footbed, shaped to support the arch and heel the way the brand's other styles do. The buckle strap lets you adjust the fit across the top of the foot, and the slip-on shape makes it easy to put on and take off.
