The Original Footbed

A footbed that moulds to you

The Boston is built around the famous Birkenstock cork-and-latex footbed. It cradles your arch, cups your heel and gives your toes room to spread. The more you wear them, the more they shape to your foot — for support that feels made for you.
Easy Slip-On Comfort

On in a second, comfy all day

The closed-toe clog design slips on and off with no fuss — no buckles to fasten, no laces to tie. Just step in and go. The adjustable strap lets you dial in the fit, while the roomy toe box gives bunions and wider feet space to relax.
Wear Them Everywhere

From the kitchen to the high street

Soft suede or smooth leather, a cushioned cork footbed and an easy closed-toe shape — the Boston works year-round, indoors and out. Wear them with socks in the cooler months or bare in summer. The pair you’ll reach for every day.

Good to Know

Common Questions

Are Boston clogs good for sore feet?+
Many customers with aching arches, bunions or wider feet tell us the cork footbed brings welcome comfort compared with flat, unsupportive shoes. The cork moulds to your foot over time. For a specific condition, it’s always worth a word with your GP or podiatrist.
How do I choose between Regular and Narrow fit?+
Regular fit suits most feet, including medium-to-wide. If you have slimmer feet or the clog feels loose, choose Narrow and adjust the strap. The size guide on this page helps you measure.
Can I wear them with socks?+
Yes — the Boston is a year-round favourite. Wear it with cosy socks in the cooler months or bare in summer. Many size up slightly if they plan to wear thicker socks.
Do they need breaking in?+
A little. The cork footbed starts firm and softens as it moulds to your foot — most people find a week of shorter wears does the trick.
Are these genuine Birkenstocks?+
Yes — every pair is genuine Birkenstock Boston, with fast UK delivery and a 30-day returns guarantee.
