Usually, men should not automatically size down in Birkenstocks. The brand’s fit is meant to look and feel a little roomier than a typical sneaker, with small gaps at the heel and toes so your foot can flex naturally. The right size is the one where your heel sits centered in the heel cup and your toes don’t touch the front edge when you walk.
Sizing down may work if you’re consistently between sizes and prefer a snugger sandal, or if you have narrow feet and feel like your foot “floats” side-to-side even after adjusting the straps. It can also help if your toes sit far back from the front edge in your current size and there’s excessive empty space at the heel.
That said, sizing down shouldn’t cause your heel to ride up on the back rim or your longest toe to bump the front lip during a step. Birkenstocks break in, but the footbed doesn’t magically become longer—so a too-short size rarely becomes comfortable later.
A good starting point is to aim for a few millimeters of space behind the heel and in front of the toes. Your arch should line up with the footbed’s arch support, and the toe bar should sit under the area where your toes naturally bend. If the arch support feels too far forward or back, that’s often a sign the size is off (not just the straps).
Also check strap adjustment: you generally want enough room to slide a finger under the straps without forcing it. Over-tightening can make the sandal feel “too big” when it’s really just misadjusted.

If you’re between sizes, choose based on length first: your toes and heel should not touch the edges while walking. If both lengths seem workable, pick the one that keeps your arch and toe bar aligned, then fine-tune security with strap adjustments and the correct width.
