What does S3L FO SR ESD mean?

S3 covers a composite toe cap, puncture-resistant midsole, antistatic properties, energy-absorbing heel and a water-resistant upper. FO means the outsole resists fuel oil. SR means slip resistant. ESD means the shoe safely conducts static electricity to the ground.

Is the toe cap metal free?

Yes. The Colly uses a composite toe cap rated to 200 joules and is fully metal free, so it stays lighter and less thermally conductive than steel and will not trigger metal detectors.

What is the difference between ESD and antistatic?

Antistatic limits the build-up of static charge for general safety. ESD keeps the shoe within a controlled resistance range so sensitive electronics stay protected from static discharge.

Is the Colly suitable for kitchen use?

Yes. The water-resistant upper, slip-resistant outsole and puncture-resistant midsole make it a practical choice for commercial kitchens, especially heavy-duty back-of-house roles.

Shoes fitting and sizing guide

Our chef shoes fitting and sizing guide helps you choose the right Shoes For Crews and catering footwear. Sizes follow EU standards. If you are between two sizes, order half a size up. We show only available sizes on the product page. If the shoes do not fit, you can return unworn pairs within 14 days.

Try shoes in the late afternoon or evening, when feet are at their largest.
Always test shoes with the socks you usually wear for work.
If you use insoles or orthotics, account for the extra volume. Replace removable insoles with your own if needed.
Pick a model that matches the shape of your foot.
The widest part of your foot should match the widest part of the shoe. The shoe should be as wide as your foot and about 1.3 cm longer than your longest toe when standing.
Move your toes to check that there is enough toe room.
Avoid shoes that are too narrow. This prevents heel slip and gives a secure fit across the top of your foot.
Boots give more support and last longer, but they are heavier and less flexible at the top.
Wear the shoes indoors on a clean surface for a few minutes to test comfort before use at work.
Feet grow as you age, so check your size again if it has been a while.
Do not expect narrow shoes to stretch. They will not.
Thick soles absorb impact on hard floors.
Laced or hook-and-loop fastenings give a more secure fit than slip-ons.
Low-heel shoes are safer and more comfortable for long shifts than high heels.

At ChefsCotton, we know how important the right fit is, for clothing and shoes alike. Any questions about sizing? Reach out to our Customer Service team. We're happy to help you find the perfect fit!
