The Mogami Terra sandal takes the outdoor collection even further. Feel comfortable to explore on a waterproof contoured footbed with added toe protection. Featuring a rugged PU sole directly attached to the footbed, this trail-ready style is designed to last, with greater durability, flexibility and all-terrain grip. In Birko-Flor® that's as smooth as it is easy to clean. Go off the beaten path.

Features
  • Water-resistant PU footbed. An anatomically shaped PU footbed with added texture and toe protection, water-resistant rather than cork, so it shrugs off a soaking.
  • Water-friendly build. Quick-drying throughout, on a water- and dirt-repellent sole — this is the Birkenstock built to get wet.
  • Rugged PU outsole. A rugged PU outsole with all-terrain grip, for ground a classic cork sandal would not take on.
  • Adjustable straps. Adjustable straps dial in a secure, custom fit, which matters once the ground is uneven.
  • Birko-Flor upper. Birko-Flor is a tear-resistant, easy-care synthetic exclusive to Birkenstock.
Size & Fit
  • Birkenstock uses EU sizing and runs large — order one size down from your usual US size.
  • Unisex sizing.
  • Adjustable straps dial in a secure, custom fit.

Widths: Regular vs. Narrow

Birkenstock styles come in two widths. Regular fits medium to wide feet (women's width equivalent C - D; men's D - EE). Narrow fits narrow to medium feet (women's width equivalent A - B; men's B - C) - the Narrow width fits most women's feet. Look for the footprint icon online and on the shoe box: an outlined footprint means Regular width, a filled footprint means Narrow width.

Testing the Fit

Before trying them on, flex the footbed by placing one hand under the toe and one under the heel - this begins the break-in period. Open all the straps, step in, then fasten them comfortably. Your toes should not touch the edge of the footbed; aim for about 1/4 inch of space around your foot. While breaking them in, keep the straps loose at first, wear them around the house for 1 - 2 hours at a time, and gradually increase wear time as the footbed molds to your feet.

Questions, answered

Ask a question
Do these run large?

Yes — Birkenstock uses EU sizing and runs large. We recommend ordering one size down from your usual US size.

Is the Mogami Terra water-friendly?

Yes — the PU footbed and sole are water-resistant and quick-drying, so it handles water, rain, and wet trails with ease.

Does it have the cork footbed?

How do I clean them?

Rinse with water and wipe clean, then air-dry away from direct heat.
