FAQs

What's the difference between BLOC OPEN and BLOC CLOSED?
BLOC OPEN model includes openings in the front that allow higher breathability of the foot, while BLOC CLOSED is completely closed at the front.
In case I purchase a style without strap, can I purchase and apply the straps further ahead?
Yes, BLOC clogs are prepared for a quick and easy application of the strap.
Is the personalization service available in all colours?
No. The strap customization service is not available for yellow straps.
Are these clogs heavy?
Each clog weighs 330gr, not being classified as one of our super light shoes. Their weight is related to their material, which allows them to be washed up to high temperatures or even sterilized in an autoclave, ideal for the hygiene demands of operating rooms, labs and other clean rooms.
Can I wear this model without socks?

We recommend our clients to check our Size Guide and follow the measuring instructions to obtain an accurate size recommendation.
