Koel Shoes Size Guide - Techbare men's sole

Here is the Koel Shoes size guide, specific to all men's Techbare sole models (Nico and Nilo models).

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

  • Leave an excess length of 0.8 to 1.2 cm depending on your 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 NILO Fabrics at Cacles Barefoot – Quick-Dry Synthetic Materials, Ultralight and Men's Barefoot Gym and Training Shoes

The Koel NILO Fabrics are the men's barefoot gym and training shoes designed for adults who prioritize freedom of movement, maximum biomechanical performance, and lightness in every session. Available at Cacles Barefoot, these trainer shoes stand out for their ultralight construction weighing only 119 g, their synthetic upper with quick-dry, highly breathable rubber panels, and an ultrafine rubber sole 4.2 mm thick that improves proprioception and stability for all types of exercises.

Why choose Koel NILO Fabrics men's barefoot gym and training shoes at Cacles Barefoot?

  • Synthetic outer shell with rubber reinforcements (Synthetic and Rubber): Made with technical synthetic materials and quick-dry rubber panels that keep feet cool during the most intense workouts.

  • High-performance ultralight design (119 g): A structure that minimizes effort, increases confidence with every step, and favors faster, more precise, and fluid movements in the gym.

  • Breathable synthetic inner lining: A soft, technical internal coating that prevents chafing and irritation from repetitive friction.

  • Reinforced protections on the toe and sides: These include strategic rubber guards to protect the footwear from wear and provide greater stability during lateral movements.

  • Precise fit with sports laces: A lacing system that allows for micro-adjustable tension on the instep to ensure a firm and stable footing during lifts or jumps.

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

Benefits of the Koel Barefoot design (Barefoot Extra Wide)

  • Ultrafine minimalist sole (4.2 mm): A 4.2 mm thick rubber base that optimizes ground feel, body posture, and natural movement technique.

  • Barefoot feeling (Zero Drop): A completely flat sole without heel elevation that provides a neutral and stable base for squats, deadlifts, and strength exercises.

  • Anatomic Barefoot Extra Wide last: A roomy space in the toe box designed following the actual anatomy of the male foot to allow the metatarsals to splay and support with total firmness.

Cleaning and maintenance tips

  1. Regular cleaning: Gently wipe with a damp cloth after training. Avoid using harsh chemicals or abrasive cleaners to preserve the technical materials.

  2. Shape care: After each use, let the shoes air out at room temperature and place paper inside to help maintain their original shape. Avoid placing heavy objects on top of them.

  3. Air drying: Keep them away from direct heat sources (radiators, heaters, or direct sunlight) to prevent discoloration and degradation of the synthetic materials.
