Koel Shoes Size Guide - Worker Sole

Here is the Koel Shoes size guide, specifically for all models with the Worker sole (Gavien models,...).

Please note that the measurements are for the interior capacity of the shoe (taken with Plus12 and Clevermess). Therefore, we advise the following:

  • Leave an excess length of between 0.8 to 1.2 cm, depending on preferences and foot morphology.
  • Also, leave an excess width of approximately 0.3 to 0.5 cm.

Due to the handmade nature of the footwear and individual measurement methods, there may be a variation of a few millimeters.

Koel Gavien Leather Black at Cacles Barefoot – Natural Leather, Timeless Chelsea Design, and Unisex Black Barefoot Chelsea Boots

The Koel Gavien Leather Black are the unisex black barefoot Chelsea boots designed to offer maximum timeless elegance, easy on/off, and total freedom of movement in any urban environment. Available at Cacles Barefoot, these boots stand out for their refined aesthetic in premium smooth black cowhide leather, dual side elastic panels for full flexibility across the instep, a chrome-free eco-friendly interior lining, and the iconic flat, flexible sole from Koel.

Why choose the Koel Gavien Leather Black unisex barefoot Chelsea boots at Cacles Barefoot?

  • Premium natural cowhide leather: Made from high-strength, flexible smooth leather that adapts ergonomically to the contour of the foot, offering durability, natural breathability, and a sophisticated look.

  • Classic Chelsea design with side elastic panels: Features wide elastic bands on both sides that allow the foot to be slipped on and off quickly and effortlessly while maintaining a comfortable fit around the ankle.

  • Chrome-Free Leather interior lining: An internal lining made of soft, hypoallergenic eco-leather that absorbs moisture, promotes thermal regulation, and prevents irritation or unpleasant odors.

  • Removable and recycled flat insole: Includes a fully removable smooth insole made from recycled materials, facilitating daily airing of the footwear, hygiene, and regulation of the internal volume.

  • Functional back and front pull tabs: Equipped with textile loops on the shaft that help slide the foot inside with complete comfort and without deforming the heel counter.

  • Ethical manufacturing in the European Union: Designed in the Netherlands and handcrafted in Portugal under strict EU environmental and labor standards.

Benefits of Koel's barefoot design

  • Barefoot sensation (Zero Drop): A completely flat sole with no heel elevation that encourages an upright posture and neutral biomechanical spinal alignment.

  • Anatomical wide shape (Wide Toe Box): A very spacious toe box designed following the real shape of the foot, allowing the metatarsals and toes to expand freely with every step.

  • Flexible, low-profile rubber sole: A thin, fully malleable rubber base that offers excellent proprioceptive response, lightness, and great grip on asphalt or urban surfaces.

Leather cleaning and maintenance tips

  1. Routine cleaning: Remove accumulated dust or surface stains by wiping with a cloth slightly dampened with water or a soft sponge.

  2. Nourishment and water-proofing: Periodically apply a neutral nourishing cream or balm to keep the leather soft and supple. We recommend spraying with a waterproofing agent to protect the leather against water splashes and dirt stains.

  3. Elastic care: Avoid applying waxes or greasy creams directly on the textile elastic panels to preserve their original elasticity.

  4. Drying at room temperature: If the interior gets wet, remove the insole and let it dry naturally in the shade in a well-ventilated area. Avoid direct exposure to radiators, heaters, or intense sunlight to prevent the leather from stiffening.

Add a timeless classic and full respectful comfort to your outfits with Koel at Cacles Barefoot!
