  • Care and Cleaning

    The clog is machine washable up to 90°C and sterilizable with the insoles in an autoclave at a temperature between 121 and 134ºC for 15 minutes. When machine washing, pack the footwear so it does not come into direct contact with the inside of the machine. Don’t use aggressive detergents, solvents or corrosive products. Let the clogs dry entirely at room temperature. Keep away from heat sources. The model’s durability depends on factors like the type of ground, hours used, the user’s weight, etc. The clog can be damaged by chemicals such as citric acid, mineral oil, petrol and diesel.

  • Frequently asked questions
    • 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.

    • Are these clogs heavy?

      Each clog weights 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 advise wearing our shoes always with socks, ideally 100% cotton, for greater comfort and humidity control.

    • Will this product widen after continued use?

      These clogs are produced with SEBS, a material that, contrary to other products made with leather, textile or other materials, is not flexible nor widens with repeated use. We recommend our clients to check our Size Guide and follow the measuring instructions to obtain an accurate size recommendation.
