A dedicated OR shoe you can disinfect
Birkenstock Super-Birki
The only option here with a published wash-and-disinfect temperature.

Washable professional clog
- Fluid-resistant polyurethane
- Removable cork-latex
- Birkenstock states 60 C / 140 F for the clog; one retailer gives 86 F for the footbed
- EN ISO 20347:2022 OB SR and ASTM F3445-21 SR cited by medical suppliers
For a shoe that lives in the department and gets cleaned rather than taken home, the specification here is the best available: a fluid-resistant PU upper, certified slip resistance to named EN and ASTM standards, and a published 60 C figure for washing and disinfecting the clog. The cork footbed comes out and is replaceable separately, so the shoe outlasts its footbed. Remove it before washing - one retailer gives a much lower figure for the cork.
What it gets right
- The only clog here you can genuinely disinfect at temperature - Birkenstock publishes a wash figure
- Removable cork-latex footbed, replaceable separately when it packs out instead of replacing the shoe
- The cork footbed molds to your foot over a few weeks, which is a different mechanism from foam compressing
- Slip resistance is certified to a named standard, not implied
What it gets wrong
- Listings disagree on the outsole material (PU in some, EVA in others), so confirm the article number before you buy
- Cork-latex needs a break-in period and feels unforgivingly hard for the first week
- Open back, so the heel-retention problem applies
- Looks utilitarian in a way that bothers some people
Who should skip itYou want comfort out of the box. A cork footbed is a two-to-three-week project before it fits you, and plenty of people give up in week one.
